A type of cannabis smoked mostly in the North East of England.
Brown and hard, but goes soft when warmed up in order for the dealer to cut it into different sizes.
Only 2% THC.
Lasts alot longer than skunk.
The best way to smoke it is with a bucket/boosh or a bong but you have to burn the tac off and sprinkle it in the chillum or pipe.
Tac joints make nasty rockies which burn through clothes.
First person: Hey, want a bit of this tac joint?
Second person: No man, I can't be getting rockie holes in this jacket, sort us a boosh though?
First person: 'Kay, but I can't be arsed sprinkling it, you do it.
