Yes If i understand correctly MAOI activity increases the effects of amps. I smoke a ton on amps but cant really say if it increases the effects much, but thats already high dose meth, might be more noticable with other amps.
Remember Nicotine alone can be considered a nootropic (based on limited research on the topic), while not responsible for the above effect, changing to ecig with nic only is far better then smoking, and even somewhat useful depending on your opinion on this topic. I get zero negative effects from an ecig like i do with cigs (like anxiety etc) and it still seems to provide the minor mental enhancement cigs did. Obviously its not something you want to start taking but its an interesting fact to know if you smoke or use ecigs.
Im still struggling to change over compeltely, there is still something about a cig effect that it cant replace, even thought they make me feel more shitty. I miss that strong effect and all that smoke but ecigs replaced them surprisngly more easily then i would have thought. I lasted 2 weeks on them, time to try agian. Oh yes and refilling the thing almost daily is the most annoying aspect as its time consuming and irritates me. And I get paranoid about spilling the liquid on my hand and dying of nicotine poisoning lol.
