ScienceDaily Summary:
A recent study looked at marijuana and alcohol use in people between the ages of 18 and 24. It’s probably not surprising that the results show a drastic increase in alcohol consumption in people just over 21; after all, that’s the minimum legal age to drink. What an economist-researcher found remarkable is that, at the same age, there was an equally dramatic drop in marijuana use.

ScienceDaily Summary:
While cannabis alters the functions of neurobiological circuits controlling appetite, its effect on weight gain is complex since several factors appear to be involved. The main finding of the study shows that long-term cannabis use indeed influences weight gain, although its effects may differ by gender.
