We can swing together

Everybody knows that.
At last,
an academic study has finally proved that cannabis gives people the munchies after discovering that legalising weed prompts a huge increase in junk food sales.
This  analys showed that the legalisation of recreational marijuana in states like Colorado, Oregon, and Washington led to a 3.1% increase in ice cream purchases, a 4.1% increase in cookie purchases, and a 5.3% increase in crisp purchases soon after weed was made legally available to buy.

These might seem like small numbers, 

said Michele Baggio, assistant professor of economics in The University of Connecticut,

But they’re statistically significant and economically significant as well.

Man doesn't need any of those, can live full his life without any drugs or junk food.
