Effects - Are small doses of methamphetamine safe?

[DeadInside]

Note: skip to the summary at the end if you cant be bothered reading the backstory

SWIM has a serious problem. Since his early teens (and possibly even earlier), SWIM has had difficulties staying focused, suffer social anxiety, and has had a fairly limited variety of activities that interested him.

SWIM is also very intelligent, and he uses it to balance out the ADD-like symptoms, and to hide it from everyone.

The problems gradually get worse as swim gets older. SWIM is 18 now and SWIM is finding life very difficult to handle, SWIM's need for stimulation is growing ridiculous to the point where only a few activities stimulate him, and the stimulation he gets from them is declining. SWIM's anxiety is getting worse and worse. The amount of willpower required just to do regular tasks is crazy.

SWIM recently tried Crystal Meth. SWIM found that in small doses (oral), all of his issues are fixed. SWIM is able to find enjoyment in more activities, he feels motivated to do stuff, he does not feel anxious or paranoid around people and enjoys socializing, he feels a wide variety of emotions that he hasn't felt for a very long time. He does not feel "high" at all, and it doesn't affect his appetite/sleep like it does in larger doses.

SWIM does enjoy the high he gets from smoking large amount, however he would much rather just take enough to be able to function like a normal human being, and large doses will likely make his problems worse in the long run.


Summary:
Basically, SWIM has two options:
Dont use meth at all, and continue living like this until SWIM reaches the point where he is too anxious to be around people at all, too unfocused to be able to work at his job, and so demotivated that nothing will bring him enjoyment.

OR

Take a small amount orally every day, and enjoy life, but risk becoming completely dependant on it to function.

SWIM wants to know if the harsh effect meth has on the brain's dopamine functions still happens when taken in very small doses (amounts that dont get you anywhere near high, but do give you increased motivation)


SWIM realizes longterm, he is fucked either way. Might aswell choose the lesser of two evils.

Much thanks for any help you can give
