i got a dmt vape its advertised as .4g per .5ml and the pen itself is a ccell flexcell pro, first time i tried i just got some pressure in my head and was really hard to smoke tonight it was easier to smoke and the effects were stronger and affected my upper body as well and a ringing in my ears but still nothing visual. am i not hitting it hard enough or is the pen just shit i cant find anything about its voltage output, im wondering if i should try transfering it to a 510 cart
