Yeah...that's pretty much how to do it. Except, I would suggest placing the tar near one of the edges of the foil, not the middle. Then hold the flame underneath the foil, while holding the foil at an angle, so the tar runs down the foil as it melts. You'll get much more smoke this way.
ALSO...instead of a straw, you should inhale the smoke using something shaped like a funnel. I used to roll up one of those magazine subscription cards so that one end was very wide, and the part you put in your mouth is small. This way you can catch more smoke.
Chasing the dragon is a blast! But I would never even attempt smoking powder. As other have said--it seems like it would be a gigantic waste...
