Higher concentrations of tetrahydrocannabinol or THC – the part of the marijuana plant that makes you high – are causing more people to become addicted in many parts of the world, a new review of studies found.
Compared with people who use lower-potency products (typically 5 to 10 milligrams per gram of THC), those who use higher-potency cannabis are more likely to experience addiction and mental health outcomes, according to the study published Monday in the journal Lancet Psychiatry.
Scientists have established a “standard THC unit” of 5 milligrams of THC for research. That amount is said to produce a mild intoxication for nonregular users.
“One of the highest quality studies included in our publication found that use of high potency cannabis, compared to low potency cannabis, was linked to a four-fold increased risk of addiction,” said study coauthor Tom Freeman, a senior lecturer in the department of psychology and director of the addiction and mental health group at the University of Bath in the United Kingdom, in an email.
