So, do you roll your spliffs with tobacco? - No.
If yes, why do you do so, and how much tobacco do you use? - I used to, but stopped 4 years ago - but I used to use between 15-25%.
If no, why not? Have you tried it before? WHy not? - the reasons below; yes Ive tried it, I'm from the UK, where I'd estimate between 90-95% of ganja puffers smoke it with tobacco.
Also, do you smoke cigarettes? - No I got out of that silly addiction a while ago.
The fact is tobacco in joints is an adulterant...it's a poisonous herb, tobacco is - you can use it for weed killer on your (ganja) plants and it's pretty effective.
Smoking ganja pure is a much clearer, less sedative high, than it is when mixing with tobacco, plus being addicted to tobacco SUCKS.
