I can choose what kind to make, how strong, and the best part is I don't have to inhale or buy something that I don't know what the long term effect will be.

I prefer to smoke cannabis. But I make wonderful concentrates at home.
I grow my own pot; from the trim and not so pretty buds, I make everything else.
I’ve been doing this a long time and I’ve finally got it down to a science.
My vape juice, for example, is pure. I add only terpene oil to the concentrate in order to get a flowing oil.
I’ll be happy to share my methods if anyone wants to know.

I don't think anyone is making butane product anymore. The latest craze is heat pressed. Vaping has a slightly different effect than smoking.
