As a novice vape--ee I,ve noticed that if i have a spliff (just say no kids) pain gets more niggly in fact I personaly feel pain more so have maintained cannabis is ineffective as a pain killer, then along came the Flashvape. A good bowl of 'Strange,s old throatsock' and it realy helps as part of a pain mannagement regime. The flashvape is a wonderfull piece of engineering and with practice you can have complete control on temps and size of dose but its deffinately for the big boys and needs a better power supply (one battery one bowl) other than that if Jesus went to buy a vaporizer, thats the one he would choose
