Unfortunately I have accident related nerve damage in my left shoulder - a side affect is my left hand shakes constantly, when it gets particularly bad I may be able to hold my hand relatively steady but by the time 2 seconds have passed I will have a spasm and the end result will be a huge zorro stripe of nicotine up the walls. And, or course, it is sods Law that I'm left handed and I find doing anything more complicated than scratching my arse with my right hand challenging.
I've considered the more concentrated food additive option, but as I only vape approximately 60ml of DL juice, and maybe 5ml of 20mg MTL salts in an average week a £100 will buy enough long dated shots to last me 4 years, so I can live with that. Obviously future taxation levels could make me reconsider
