Marijuana use has recently been linked to triggering earlier puberty as well as stunting growth in boths, according to a study out of Pakistan’s Pir Mehr Ali Shah Agriculture University Rawalpindi. This study is the first of its kind to take a look at the effects of cannabis upon pubescent boys and how hormone production is affected during this stage of their lives.

“Compared with nonusers, boys who used marijuana had higher levels of puberty-related hormones, including testosterone and luteinizing hormone. However, the team also identified reduced levels of growth hormones among boys who used marijuana, compared with nonusers. From analyzing the height and weight of all boys, the team found that those who did not use marijuana were an average of 4.6 kg heavier and 4 inches taller by the age of 20 than those who used marijuana.”
