Just another mainstream drug, that mainly losers use.
Losers being people who are so dissatisfied with their lives, that they have to be under the influence of something to be able to actually endure it. And instead of doing something to better themselves, they get high.
Also very popular with angsty teenagers and immature adults.
If that isn't a good enough reason NOT to smoke it, it also smells like shit.
"Hey guyzzzz lets smoke some Marijuana!"
"Yea because its SOOOOOO cool!!!"
"If you don't smoke weed ur soo lAME!!!11!"
