A friend of mine claims that meth actually helped him in his studies. He claimed that once snorting, he gets so much energy and focus that he was able to learn all he had to learn for his finals in one night. Now that we are graduates, he still uses and is still claiming that it helps him concentrate in learning songs (he works in music). I've seen on movies and tv that acid and to some effect weed helps musicians get songs down. But I never heard of meth having the same effect. Is there some validity to his claims or is he just making excuses to continue? Kinda worried about him.
