Okay
Pretty good but you are quite incorrect about your information regarding usage. Methamphetimine ingestion through IV (needle) use is often a last resort for a user that has developed a tolerance to smoking it, and after their nasal linings have been destroyed from snorting. IV use is even among users an often frowned upon and often hidden activity even amongst other users.
For the most part most meth users wont even hang around a needle user because by the time the user has progressed to that point they have a tendancy to steal, prostitute themselves and flat out rob someones ass to get high, and even most drug addicts just dont want that drama.
I know im right, because ive been in recovery for 2 years and have successfuly kicked the stuff with Treatment and Support from family/ friends. Your teacher is wrong, not stupid. just misinformed. Thought you'd like to know. After all you did research it. Thought obviously not very much, 6
