Its pretty amazing the cost of herb on a per bowl basis when using a vaporizer. I figure I spend about $1 per bowl if even that. Since $1 will accomplish the task I find it just insane from a afford ability aspect of herb. I usually do 2 bowls on a night that I decide to light up. But compared to Alcohol(which I despise, but may use once a year) that $7-$15 with take home brew or a ton more if bought it buy the drink. Think of what you get for a $1 of herb and I think you'd have to agree its a remarkably low price.
