its a simple as this, for some weed is good, for some its bad, i sell weed to many types of people, the heaviest smokers are losers, simple as that, have you ever known anyone who smokes 3 ounces a week who isnt probably mad, coz i dnt, im probably 1 of the heaviest smokers in the uk, i smoke a half 0 to 0 a day, usually a bit more, today i had an argument with my cat, nuff said bout that ,the moderate smokers (ounce for up to 4 weeks) are not all there, cant rememba anything and are paronoid 24/7, the light smokers are ok, they just cant handle it when they smoke with me coz i smoke too much and they start puking and shit, as far as i can see, if you dont do drugs to escape reality youl be fine, if you use mind altering substances to escape a shitty life or the skeletons in ur closet then ur gna have a fuck load of problems.
