growing weed is a hassle, fun, but fucking diffucult to get the exact conditions u need for a decent crop (involves monitoring nitrogen, and potassium levels in the soil, complicated lighting schedules etc) PLus u have to wait 10 weeks min to grow, and a couple to dry. So most stoners would opt to buy from shop IMO. Plus stoners dont make the most competent of horticulurists.

I think in the UK, cannbis was the 4th largest constiuent of our economy ahead of fast food (has been years since i saw this in the paper so might not be 100% accurate)

Legalising weed would bring in a fuck load money for the government

However Labour are already getting enough stick for downgrading cannabis to class C (a verbal warning if caught with say an 8th), so i can see legalisation being ridicously contreversial, let alone in your country with the religous right
