Ok so SWIM recently obtained some DMT and after doing some research on best methods to vape/smoke it decided to make a very crude but simple rig.....SWIM cut the bottom of an empty 2 liter bottle off, wrapped a layer of aluminum foil around the opening at the bottom and attached it with one rubberband. Next SWIM removed the aluminum foil and put a slight indentation in the foil to hold the DMT, placed a strong dose inside reattached the foil to the bottle and started to light the underside with a regular bic lighter keeping the flame about an inch away from the foil and kept rotating the flame to prevent burning the DMT. So now after a minute or so the bottle was quite full of vapor SWIM couldnt see his hand through the bottle and noticed the DMT was basically all vaped. Then SWIM unscrewed the cap inhaled all the vapor quite easily in one fast strong pull sat back and screwed the cap back on and set it down. Now SWIM understood going in that you need to hold the vapor in for as long as possible but as soon as the bottle was placed on the floor and SWIM was holding the hit in the trip started to come on immediately and very strongly SWIM got scared at the speed and intensity of the trip and exhaled the vapor after maybe only a second or 2...SWIM is quite sure the dose was enough to breakthrough but not holding in the vapor long enough was SWIMS mistake I believe. My question is how can one deal with the intensity of the trip while still being able to hold in the vapor when using this paticular one hit breakthrough method?
