I wouldn't say I smoked heavily, I definitely smoked almost every day though.. but only like 3-4 bowls a day..(which i guess could be considered heavy to some people lol). But to answer about the drug test, nope not yet.. I ordered one and it came in the mail yesterday.. Just gonna wait a few more days till I test myself, cause it technically hasn't been a month yet.. This wednesday will be a month. Now, what is considered "heavy" smoking? Cause like I said, i only smoke a few bowls a day, and to the average person, they are relatively small bowls.. Id say 3-4 hits a piece.. I am about 6ft, 215.
