What is considered to be "heavy usage"

[killerweed420]

ok let me ask u this if u where on probation and didnt have to see yer po but every 3 months would u smoke

If you want to play the game pickup some thc test strips and test yourself at home. I get mine off ebay for about $1.30 each.
But as has been stated analyze the threat to see if its worth the risk.
I use to be able to smoke a couple days and then stop for 3 or 4 days and be clean enough to pass but everyone is different.
