im no expert but i think the active ingredient is tar.
True, but does that add to the Red Bull flavor?
Good guess anonymous guy, but I know for a fact that molasses like Starbuzz have 0% tar and 0.05% nicotine. Normally molasses is baked instead of burnt and runs a filter through water. This is why you don't get harsh smokes from hookahs vs cigarettes. Nicotine itself burns up in the air at 95 degrees Farenheit. 0.05% = 50 g/kg and a bowls usually only hold 25g. 0.5 kg is lethal but you would have to smoke like 500g of molasses which is ridiculous.
^ holy smokin' science batman :P
