Hash Now 25% Stronger Than 50 Years Ago, New Study Reveals

Science & Tech News - Hash Now 25% Stronger Than 50 Years Ago, New Study Reveals

Cannabis resin, or as it is more commonly known — “hash,” has drastically increased in potency over the past 50 years. In fact, a huge international study just revealed that it did so by an astounding 25%!

A group of researchers working in chorus with the Addiction and Mental Health Group at the University of Bath analyzed the data from over 80,000 cannabis street samples collected over the course of 50 years in New Zealand, Italy, Denmark, France, the Netherlands, the UK, and the US. 

According to these mind-blowing findings published in Addiction, there has been a noticeable change in the concentration of THC (the cannabis compound responsible for getting you “high”) over the years. More specifically, between 1970–2017, THC concentrations increased by a whopping 14% in herbal cannabis, mainly due to the current market share offering more potent varieties; for example, sinsemilla. 

As for the cannabis resin extracts, these have risen by a whopping 24% between 1975–2017. In other words, THC concentrations have been slowly increasing by some 5mg per year. And according to researchers, even a single 5mg dose can cause mild intoxication.

The lead author of the study, Dr. Tom Freeman, claimed that cannabis has continued to rise in potency over time; so much so that it is now a completely different drug than it used to be some 50 years ago. Dr. Freeman also added that the attitude around cannabis has also shifted, with an increasing number of people claiming the drug has a plethora of benefits for both mental health and medical use.

The co-author of the study, Sam Craft, claims that cannabis resin, or hash, is often regarded as a safer form of marijuana. Craft also added that, traditionally, hash contained less THC with an equal amount of cannabidiol. However, cannabidiol concentrations have more or less stayed the same, whereas THC content has increased considerably.
