Here’s Some Good News for People Who Smoke Their Weed with Tobacco
Smoking weed with tobacco doesn’t improve the high, according to new research conducted by University College London. This study counters the long-held stoner myth that a drop of tobacco will somehow magnify the effects of the cannabis. However, it’s not all bad news: The study found that the combination may actually reduce the damaging effects cannabis can have on memory.
In the first study of its kind, scientists examined the effects of the two substances when combined and inhaled, and subsequently debunked the popular myth that it increases or impacts the high. Their research suggested that improvements to memory could be down to the fact that nicotine has been proven to sharpen the mind.
As for the negative impact of combining the two, don’t fear: UCL also looked into those. Smoking a mixed tobacco and cannabis joint can also temporarily increase blood pressure and heart rate, which doesn’t sound so positive.
The investigation involved 24 people smoking various kinds of joints, either with tobacco or a placebo. The participants were then subjected to memory tests and had to recall passages of text they had heard pre-smoking. In addition to this, the group had to complete a given task to assess another side of their memory.
As for the physical effects, the volunteers had their heart rates and blood pressures measured before and after, while their experiences and moods were noted too.
Chandni Hindocha, lead author of the experiment and a researcher at the university’s clinical psychopharmacology department, told the Daily Mail: “There’s a persistent myth that adding tobacco to cannabis will make you more stoned, but we found that, actually, it does nothing to improve the subjective experience. Surprisingly little research has been done on how tobacco might alter the effects of cannabis.”
This research is particularly relevant to the UK. According to the latest Global Drug Survey, up to 90 percent of European cannabis smokers add tobacco. On the other hand, research indicates that US counterparts are more likely to smoke it on its own.

A Strange Blend: Why Are Europeans Mixing Cannabis and Tobacco?
This article was originally published on Leafly.
Cannabis doesn’t carry the sort of health hazards tobacco does, a majority of studies say. But that doesn’t change the European habit of mixing the two. It’s something North American cannabis consumers don’t often do: even cigarette smokers in Vancouver or L.A. tend smoke their flower pure, strictly separating nicotine and cannabinoids. So where does this difference come from?
To answer the question, let’s go back in time to the cannabis renaissance of the 1960s and ‘70s. Consumers in Europe at the time almost exclusively smoked hashish, often crumbling it into cigarettes, as hardly anyone was aware of the dangers of nicotine and smoking tobacco. The vast majority of cannabis consumers in the U.S., on the other hand, overwhelming had access only to dried flower, which could easily be used to roll pure joints.
These differences influenced the size of what was being rolled in North America and Europe. In the U.S. and Canada, pure “mini-joints” became the standard, while on the continent a king-size joint is preferred. A European-sized joint that contains only cannabis might contain 1.5 grams to 2 grams of flower — far too much for most. An American joint, on the other hand, contains about as much herb — about 0.2 grams to 0.5 grams — as a European mixed joint (often called a spliff in the U.S.), but without the nicotine. Scientists have even pinpointed the average amount of cannabis in an American joint at 0.32 grams. In Germany, the Netherlands, or Denmark, that amount of cannabis is typically mixed with another gram or so of tobacco, depending on personal preference.
Not only does consuming a cannabis–tobacco blend affect your health more than pure flower, it also complicates efforts to gauge the health effects of cannabis itself. The legalization debate often revolves around the dangers of “smoking,” because almost every European study on cannabis is not about smoking it pure but about cannabis mixed with tobacco. Even in medical programs, little attention is paid to whether patients smoke pure. That means that Europeans who use cannabis alone has to justify the consequences of a substance that has little to do with cannabis.
Even without tobacco, smoking is the unhealthiest form of any medical application. Yet other, healthier forms of consumption, such as vaporization or edibles, seem to catch on much more slowly in Europe. That’s in part because tobacco has long been engrained in European culture; as cannabis grew in popularity among Europeans, that affected how people chose to consume. In other cultures, where cannabis has been part of everyday life for millennia, people consume orally or at least smoke cannabis pure.
Mixing tobacco into a joint increases the addictive risks immensely. Many casual users have only begun to smoke cigarettes because they use tobacco for their joints. “Without cannabis I have no problems, but I then smoke more cigarettes” — you’ll never hear such a statement from a pure-cannabis consumer. Doctors in Germany or the Netherlands treating cannabis patients are often unaware of this phenomenon and fail to advise patients to quit tobacco— or at least to separate the consumption of both drugs so the positive effects of cannabis remain intact. The unfortunate reality is that in most instances in Europe, the pairing of cannabis and tobacco simply isn’t discussed.
Last but not least, pure cannabis acts quite differently than a cannabis–tobacco blend. Patients report that the combination of nicotine and cannabis can lead to pain relief and relaxation, but very often they note fatigue as a negative side effect.
All these facts should be worrying enough for European cannabis fans to reflect on their consumption habits. To make things worse, there’s the political aspect. Prohibitionists use the dangers of the legal drug nicotine to protest against legalization of cannabis: “How can we have ever stricter laws to control tobacco and at the same time legalize cannabis?”
Professor Donald Tashkin has been a leading American pulmonologists for decades. In the past he was a vocal supporter of cannabis prohibition. Tashkin was convinced that smoking cannabis flowers created a high risk of developing lung cancer or chronic obstructive pulmonary disease (COPD). At one point, he was convinced that cannabis and lung cancer had a causal relationship worse than tobacco.
But more recent evaluations of long-term studies, however, made him change his mind in 2009: “Early on, when our research appeared as if there would be a negative impact on lung health, I was opposed to legalization because I thought it would lead to increased use, and that would lead to increased health effects,” he has said. “But at this point, I’d be in favor of legalization. I wouldn’t encourage anybody to smoke any substances, because of the potential for harm. But I don’t think it should be stigmatized as an illegal substance. Tobacco smoking causes far more harm. And in terms of an intoxicant, alcohol causes far more harm.”
If the legislators take their task to protect public health seriously, European studies that evaluate the risk potential of pure cannabis consumed in various forms (smoking, vaporizing, edibles) have to be undertaken. These studies should take the international state of research into account, focusing on safer ways of consuming.
