I make my own tinctures with everclear and bulk weed from the dispensaries (2 oz for $75 sales).

There's no cheaper way to fly. But I also have my med card so I don't pay taxes, making the cheapest 100mg gummies $4 for me. But still it's cheaper to grind, decarb, and simmer it myself.
I'll buy a THC drink now and then at the store but it's always like $5 for a 10mg can of whatever it is, so it's really not worth it.
The cheap gummies are scored so you can cut them into 10mg doses.
I pop 20 mg. when I get up usually. Today I didn't get high from bong hits until late and I just took a full teaspoon of the tincture. I don't know the strength but a teaspoon feels like about 40 or 50 mg of gummies do.

Weed makes life a little better. And thank christ for that, because I burned all my bridges with other drugs.
