Good evening everybody I'm new to this forum so please don't hate! Basically I'm back off smoking again, my x baby beast tank and alien mod didn't do it for me so I've got myself and my girlfriend a SMOK M17 Privs, I've got tonnes of 12mg and 6mg liquids for me E Cigarette, however I've purchased 5 20mg flavoured nic salt e liquids and I used to smoke 15-25 cigarettes a day. Long story short will it be safe to use in this device? I'm going through e liquid like no tomorrow and 18mg is too harsh, it's a 0.6 ohm coil, it's technically a sub ohm tank but it's not really. Sorry for the long post just want clarification, thanks all.
