before it was prohibited it cost 9 bucks for an ounce, prices will probably go up as most things do in this new day and age, but it probably would follow the tobacco pattern (5 bucks for 20 joints weighing in at .7 per joint), also people will be able grow them more openly and do alot more testing on the drug allowing in more understanding and higher levels of thc!

the only downside that i can think of, is that companies would do to the herb what they've done to tobacco... (add alot of cancerous chemicals that make it addicting)

heck, herb is so much easier to produce it would probably be less then 5 for a pack, more like 2.50$
