Zero tolerance and the need for safer drug use limits

Guidelines exist for one of the world’s most dangerous and widely used drugs, alcohol. These were developed to help people and health care professionals have some idea what different level of drinking might be associated with low, moderate and high risk of harm. They are based on evidence, and although recent epidemiological data has probably underplayed the risks for cancer, properly used (e.g. within brief screening and intervention), they can help people reduce their drinking.

The problem is similar sensible guidelines don’t exist for illicit drugs. In most countries, the government line is basically, “Do not take illegal drugs because they are all bad.”

Just for the record (and the lawyers) the Global Drug Survey (GDS) states categorically that the only way to avoid all harm from drug use is to not use them. However, it’s not a very practical goal for people who like to indulge. The reality is that the risks of experiencing harms from using drugs can actually be massively reduced for most people with the right set of advice.

This is why GDS developed the world’s first Safer Using Limit guidelines. Using data collected from the 100,000 people who took part GDS2015, we are creating a number of guidelines, starting with cannabis, aimed at raising people’s awareness of the level of risk that different patterns of drug use places them at. We did this by asking respondents to rate how the risk of harm from different drugs (including alcohol) is heightened with increasing levels of use. “Risk” here refers to the probability, range and severity of harm. The higher the score, the more likely it is for a person to experience harms and problems, with higher scores indicating an increased severity of said harms. We also asked our respondents to think about the likelihood of a person experiencing harm over the next 1-2 years. By harm, we mean anything that causes a person problems, such as mental or physical health, relationships and behaviours, finances or ability to work, study, or just do the things in life they want to do.

Our first set of guidelines (on cannabis) was launch on June 18th 2015 at www.saferuselimits.co. Over 20,000 people have got their risk score so far.

Are drug users really the best experts?

A reasonable question to ask is, how valid are risk estimates based on the votes of a self-selecting group of drug users who surely have cognitive and emotional bias to minimize the risks associated with a consumptive behavior? I don’t know, but leave it to you to decide based the composite ratings from over 40,000 cannabis users that Professor Michael Linskey used to help develop the relative risk scores – shown below.

I came up with very similar ratings when I did the exercise blind before we launched GDS2015 last year. We hope to ask experts around the world to do the same thing in a project we are trying to set up to see the level of agreement between users and “experts.” The reality is, though, that the major driver for the approach we took was the fact that the people drug users trust most are other drugs users. Simply put, guidelines on safer-use limits voted by those who like to toke will be less quickly dismissed by other stoners.

I passionately believe that for most people who choose to use drugs and alcohol, they can be a source of pleasure that enhances the rich fabric of their lives. While I understand that drug use for some people is unwise (and best avoided) either because of their age, pre-existing health conditions or other vulnerabilities, the decision to use drugs is one that must always be treated with respect. I hope our work helps people, communities and governments have more honest conversations about drugs.

Selling Alcohol in Grocery Stores: Hidden Risks and Alternative Options

This post originally appeared on the CAMH blog. While this blog is from Ontario, many of the points are relevant here in BC, now that alcohol sales will soon be permitted in select grocery stores.

In the last few days we have heard about plans to permit the sale of beer and wine in grocery stores in Ontario. For the most part, media reports have made no reference to potential health and safety risks associated with the proposed changes. You would have thought that the reporters were talking about changing the distribution of milk or orange juice in Ontario. What about the possible increase in alcohol-related incidents or negative impact on vulnerable populations — is that not relevant to the discussion?

Alcohol is a drug with a long list of well demonstrated harms associated with its use. How it is sold, marketed and priced impacts the rate of alcohol-related problems. International research over many decades has shown repeatedly that if more alcohol is sold and appropriate checks are not in place, then more harm can be expected. These harms include a range of health and social problems impacting not only the drinker, but others in society. They contribute to the already high costs of alcohol-related hospital care (chronic and emergency), criminal justice responses, and productivity losses.

Currently in Ontario there are about 1,800 places where alcohol can be purchased to be consumed elsewhere, so-called ‘off premise’ outlets. This includes LCBO regular stores, LCBO Agency Stores, Ontario Winery, Beer Stores and a few others. According to media reports, the contemplated changes would add about 400 new outlets – 100 new Agency stores and 300 large grocery stores that would sell beer and wine. This is a 22% increase in outlet density.

Canadian and international research has indicated that an increase in alcohol outlet density is associated with a wide range of acute and chronic problems. While there are many international examples to support this conclusion, a recent one from British Columbia is timely: researchers found that after an increase in private liquor stores (higher density) there was an increase in liver cirrhosis cases.

Once 300 grocery stores have a green light, will not the thousand or so others also lobby for the same access? What about convenience stores? We know from the examples of Alberta and BC that privatization of alcohol sales can result in more relaxed enforcement of laws pertaining to underage purchases – as well as higher mortality rates from suicide and other alcohol-related causes. The proposed plan is a very risky one. An alternative strategy should be developed in consultation with public health experts.

The challenges of eliminating Ontario’s deficit are likely substantial and will require innovative approaches and exemplary decision-making. As the provincial government attempts to raise revenues and “modernize” the sale of alcohol, it should focus on strategies that can achieve that aim without increasing the risk of alcohol-related harm. Possibilities include:

  • Minimum prices on alcohol could be raised
  • Product prices could be based on alcohol content, and taxation protocols could be adjusted, so that there is an incentive for production and consumption of lower-strength beverages
  • Marketing expenditures by the LCBO could be reduced
  • Further efficiencies can be introduced to the LCBO, such as using its buying power to get better prices from manufacturers and wholesalers

The course being discussed by decision-makers, in its current form, seems certain to contribute to an increase in alcohol-related harm and costs. We should encourage decision-makers to choose instead a course that fosters greater public awareness of alcohol-related risks and encourages the reduction of those risks. The health of Ontarians should come first.
