Cannabis

How often do you use Cannabis?

On a typical day of use, how much cannabis do you use?

?

Does it matter what type of cannabis I am using?

Probably yes. In short, high potency herbal cannabis (skunk/hydro) which is high in THC and low in CBD is associated with more memory problems, paranoia and is more likely to trigger serious mental health problems in young people with an underlying vulnerability to developing psychotic illness. Work done by GDS also suggests that ‘skunk’ is associated with higher rate of dependence and people wanting to use less (seems to end abruptly).

1 Very low risk

Associated risks: Accidents, short lived unwanted psychological and physical effects, increased risk of nausea/impairment if you drink

What sort of user am I?

You call the inhalation of cannabis “doing weed”. You do weed very rarely because you’re on a beach and that guy has a guitar and there’s a girl over there who looks a bit like that cute girl you almost dated, and shit, the boys back home are never going to believe what a mental night you had and how you laughed so much you almost shat yourself. If this sounds like you, you’re probably going to be alright; a couple of tokes on a spliff (assuming its not’s an ‘uber spliff’ or one laced with that nasty synthetic crap) once every 12 months is unlikely to put you at risk of long-term harm.

The risks

Consuming a small amount of cannabis just a few times year is unlikely to place you at much risk of long-term harm. Of course if you’ve never got stoned before or are very sensitive to the effects of cannabis you might not enjoy the feeling. Some people can feel nauseous, dizzy and/or sleepy. And even at very low doses some people feel uncomfortable especially around others. If you have a mental illness or family history of psychosis even these very small levels of use might be a risk for you. You might be more prone to stumbling and falling over, especially if you drink alcohol as well. But assuming none of these things happen, you’re not under 18 years old and this is not the start of you becoming a long term heavy user, the risks associated with this level of use are reality minimal. And don’t drive or get in a car with someone who’s just had a joint.

How to decrease your risk

Just Say No.

2 Low risk

Associated risks: Risks associated with lower scores + hangover effects, tobacco use, short term cognitive impairment that might impact on work performance/studying

What sort of user am I?

You know what a grinder does, but you’ve never owned one. You could probably have a crack at rolling a spliff, but it’s likely it would end up doing that weird thing where you get cherries over your favourite shirt, it just burns black all up one entire side, rendering the whole thing unsmokeable, or even worse you lick the wrong side. Cannabis is not an essential part of your life. You rarely – if ever – buy your own supply, but you’ll happily have a couple of hits if someone’s passing a joint around. Being an occasional user of cannabis - and by that we mean where cannabis is something that’s not an essential or regular part of life – it is usually a source of pleasure for people who choose to you use it like this.

The risks

Using at this level if you are smoking it (especially with tobacco) would still potentially increase your risk of respiratory harms and airways disease if you carried on for many years at this level and it might impact on your ability to focus and study if you needed to fire on all cylinders. Some might notice feeling a bit slowed down the next day. Your risk of accidental harm would certainly be an issue if you were not used to the effect of cannabis and for example, tried to drive a car (never a smart thing to do). But assuming your use did not extend over very many years, the likelihood of you experiencing any significant harm unless you were predisposed through underlying mental health issues, or being very young, is small. Driving under the influence of cannabis is associated with two-fold increase in the risk of fatal road accidents (further increased if mixed with alcohol).

How to decrease your risk

Just use a bit less and if you smoke don’t roll with tobacco. Or buy a vaporiser; they’re pretty cheap these days and enough non-weed nerds now own them that you’re not going to look like a dick when you get yours out. Also, don’t drive or cycle under the influence of cannabis.

3 Moderate risk

Associated risks: Risks associated with lower scores + potential impacts upon memory, mood, lung health if you smoke, mental health and motivation

What sort of user am I?

You’ve probably got a dealer, or at least a mate or two you can get weed off. You can skin-up in public and you’re not ashamed. You use with friends and might use a bit on your own. Whilst it’s nice to have weed in the house if you run out you don’t start hitting your roaches seeing if you can skin-up from left overs or reaching for the phone to see whose got a bit to spare. You like being stoned, but it ain’t the be all and end all and you can still get a good night’s sleep without a bed time doobie.

The risks

The use of cannabis at this level is not without risk. Regular users report concerns over their memory, mental health, levels of motivation and impact on their relationships and physical health. While more frequent use is likely to make these other issues relevant for you, using big doses infrequently may place you more at risk of acute unwanted experiences such as feeling paranoid or panicky, which although usually short lived can be unpleasant. At this level of use the issues of how long you continue to use becomes an issue – with use extending over many years eventually increasing your risk of harms. Driving under the influences of cannabis is associated with two-fold increase in the risk of fatal road accidents (further increased if mixed with alcohol).

How to decrease your risk

Again just use a bit less, a bit less often and if you smoke don't use tobacco. A vaporiser might do your lungs a favour and remember, you don’t have to inhale deeply and hold the smoke in for long to get stoned. If you’re not being quite as sharp or feeling as healthy as usual maybe give yourself a few weeks off. If you smoke tobacco then maybe try some form of nicotine replacement. If you think you use cannabis to help you deal with pain or some other problem go have chat with your family doctor, a counsellor or a mate to see if there are other ways you could try to manage those stresses.

4-6 High risk

Associated risks: Risks associated with lower scores + risks of dependence, broader health effects especially if you smoke with tobacco (including cancer)

What sort of user am I?

You’ve always got skins and weed in the house, anyone looking at your desk will spot the roach rips and you’ve got a stash box with all your bits in it. You don’t mess about buying single grams and you know more than one place to score. You can go all day without smoking but if you could fit in a cheeky spliff while at work you might. You’ve probably learned to do most things whilst you’re stoned and might try to downplay just how much you use from some people. Sleep might be an issue without a bedtime spliff.

The risks

At this level it is likely that your use may have started to impact negatively upon some areas of your life. You have almost certainly built up tolerance to the effects of cannabis and may be spending more time stoned that you planned. You might notice not feeling as sharp in the morning when you wake up after a night smoking. If you are smoking every day you might find that you don’t sleep as well as well when you don’t smoke. Just how much of an impact your use of cannabis is having on your memory, mental health, levels of motivation, relationships and physical health will probably depend on just how long you have been using and what else is going on in your life. But it would be fair to say that if you continue to use at this level the likelihood of experiencing some longer lasting unwanted effect on one or more aspects of your life from your use is a real probability. Again if you are young or have underlying mental problems this sort of level of use is likely to have quite significant implications on your future emotional, cognitive development and well-being. Driving under the influences of cannabis is associated with two-fold increase in the risk of fatal road accidents (further increased if mixed with alcohol).

How to decrease your risk

It always starts with trying to use a bit less, a bit less often and if you smoke don't use tobacco. A vaporiser might do your lungs a favour and remember, if you smoke tobacco then maybe try some form of nicotine replacement. If you think you use Cannabis to help you deal with pain or some other problem you might to find someone to help you think of other ways of coping to allow you use a bit less. Dealing with any underlying problems will make it easier to cut down on what you use. The other stuff you need to think about is whether any of the things that aren’t going quite right for you are due to your use of cannabis. If so, or even if you’re not sure, giving yourself a break or chatting to someone to help try and reduce how much you use can help. For more information have look at Cannabis – What you need to know to be healthy and A Doctor's Guide to Cutting Down at the end of these guidelines or try the cannabis drugs meter (free at Google Play or www.drugsmeter.com).

7+ Very high risk

Associated risks: Risks associated with lower scores + risks of dependence, withdrawal, negative impact on interpersonal relationships, aging and motivation

What sort of user am I?

You smell it, you feel it, you examine it, you judge it, you love it! But hate to say it – you might need it. Being a stoner is part of who you are – and you might be fine with that (or not, or maybe your other half isn’t so keen). You can skin-up in a force 10 gale, in the dark while ordering a pizza. You’re probably a bit stoned all day, but you don’t notice or maybe other people don’t either. Other people are wary of your spliffs and aren’t keen for you to skin-up with their stash because it disappears. You might wake up, skin-up, get up, in that order. When you’re down to your last bud, or see the bottom of your stash box you start to worry. You'll check your side draw, you go on carpet patrol and hope your roaches are fat. You'll start making calls. If there's no reply you'll worry. You'll arrange to see a mate – one who always has a little. Your spliffs might become skinny. You might be a connoisseur but if you’ll take whatever is going if there’s nothing else. You might smoke to cope but can’t cope without dope.

The risks

Scores in this range probably put you in the top 5% of cannabis users. Your tolerance is very high, your use is almost constant and the likelihood of there being periods of the week when you are not stoned is slim. Many people using at this level will experience a loss of control over their use, find they prioritise their use of cannabis over other activities and may notice they become irritable and restless if they run out of cannabis. At this level of use, your exposure to cannabis is likely to be impacting negatively upon your physical health – especially if you smoke and/or also use tobacco. You might well notice that your memory is not as good and your interactions with friends and work colleagues are not as rewarding / interesting /intimate or productive as they used to be.

Depending on how long you have been using at this level the impact may be more or less obvious to you. If you have been using at this level for several years you are probably in the top 1-2% of all cannabis users. The personal and emotional implications of this level of use are sometimes hard to see, especially if you have been using at this level for a while and ‘getting on with your life’. You might see yourself functioning quite well. And you might be. Other people may also see no cause for concern (or they might). Many people who use at this level only continue to do so because they can. But just because you are functioning doesn’t mean you’re not at exposed to any risk. Cannabis addition can slowly and silently make your life worse without ever getting bad enough to seem worth addressing; it may not destroy your life but you will miss opportunities and leave potentials unfulfilled and relationships wanting. More than anything else, using cannabis at this level will rob you of the one thing you can never get back – time. The chance of you making the most of all your opportunities if you continue to use at this level is way less than it would be if you used less, or less often (or both). Using less would give you back something really precious. Time.

How to decrease your risk

It always starts with just trying to smoke a bit less, a bit less often and don’t roll with tobacco. A vaporiser might do your lungs a favour and remember, if you smoke tobacco then maybe try some form of nicotine replacement. But it might be hard for you to cut down and the thought of trying to quit might be overwhelming. If you think you smoke to help you deal with pain or some other problem you might want to find someone to talk to so you can think of other ways to cope should you reduce your use or even stop. Dealing with any underlying problems will make it easier to cut down on want you use. You should also ask yourself whether any of the things that aren’t going quite right for you in life might have anything to do with your use of cannabis. If you think it might or if you are not sure then giving yourself a break of a few weeks or more, can be a great way to find out the answer. Many people who reduce or stop their cannabis use feeling brighter and healthier even if they loved using cannabis.

Given the huge evidence that drug and alcohol use before the age of 18 can cause long lasting impairments in your cognitive and emotional ability, Global Drug Survey stresses that this site is strictly for those over 18 years of age.

As ever, the only way to avoid drug related harm is not to take drugs and that no level of intoxication with any substance can be considered drug free and most importantly Global Drug Survey is keen to remind readers that the following guidelines simply represent Global Drug Survey reporting on the combined opinions of tens of thousands of people who use drugs.

1. Young brains and drugs are not a good mix

There’s a huge amount of evidence that alcohol and drug use before the age of 18 can cause long-lasting impairments in your cognitive and emotional ability. Kids don’t screw up your brains. “Grow your brain before you start expanding it” Our guidelines are strictly for those over 18 years of age.

2. Guidelines don’t make drugs safe

By developing safer drug using limit guidelines for illicit drugs Global Drug Survey is not suggesting that drugs are safe. Quite the contrary in fact. Drugs can be very dangerous and Global Drug Survey is not suggesting guidelines will be a panacea to society’s drug problems. But as governments are starting to embrace population-based strategies to improve health and think more rationally about drug policy, having some common sense guidelines that allow people to reflect upon their drug use is a sensible thing.

3. We are all different

We accept there are also a few obstacles in creating catch-all safer use limits: purities vary; drugs are rarely taken in isolation of each other; the method of ingestion can affect the risk; people’s initial tolerance may vary depending on height and weight; and, finally, lots of people take drugs for lots of different reasons, so if you’re using them to cope with other issues you may be more susceptible to experiencing harm at a much lower level.

4. People with existing mental health conditions are much more vulnerable to drug/alcohol harms

If you have a underlying mental illness you are much more likely to develop drug related problems – both short-term ones, like getting anxious or paranoid, and long-term issues such as dependence. If you have a psychiatric illness and things are not getting better taking a rest from drink and drugs can help. This may allow the treatment you are on to work better and make it easier for you and your doctors to know what’s going on.

5. Other times to take care

If you are pregnant or trying to get pregnant avoid cannabis. If you have heart or lung conditions you might want to think about your use as well.
