Drip style vape boxes underground uses

[claytyler92]

Okay so swim starting gaping a few months ago and fell in love with it, just for the flavor and to quit smoking, well swim was a regular meth user and started seeing links on Google talking about VAPE boxes being used for recreational drug use, so I tried it with descent results. Not great. Decent. Swim has a drip box vape with way the control and temp control ranging from 160 watts and 600 degrees F . Swim tried putting a tenth of crank on directly on the coils and it worked a little. Later swim took the 3ml bottle and filled it with 2 ml of vape juice that was 70/30 vg to pg and added about a half gram. Swim has been vaping on the pen since last night and defiantly felt effects but no where near what expected after hearing all the hype about it.

Any suggestions you could give swim on how to do this more efficiently?
Thanks
