According to a new study that was published in the journal Nature Neuroscience, there are 35 different genes that make a person more likely to crave marijuana.
Data used from 180,000 people determined that there is a relationship between a person’s genes and their relationship with the drug.
Some of the people had used 23andMe, an ancestry company, while others took part in 16 other studies.
The study found that the people who are predisposed to developing ADHD and schizophrenia are also prone to “lifetime cannabis use.”
“The study found a genetic overlap between cannabis use and the use of tobacco and alcohol,” the study’s authors wrote. “There was a similar overlap between cannabis use and personality types that were prone to more risky behavior or were more extroverted.
“This means that genetic variants impacting cannabis use partially impact other psychological or psychiatric features as well.”
The study also determined that someone’s genes only “helped to explain approximately 11 percent of the differences in cannabis use between people.”
