People smoke weed every day because it is legal, it is available, and because the quality is consistently excellent.
Almost 100% of marijuana smokers do it to get high.
Very different from alcohol drinkers. 75% of adult drinkers just want to relax for a half hour or catch a light buzz.
Today, for pot smokers, if you do not get thoroughly stoned with one or two hits, you ask for your money back!
Most of the people who smoke all day, every day, are just waiting to score on much more powerful illegal drugs.
The same thing happens with smoking pot. Stronger pot only means you need to smoke less to achieve the desired effect.
