I have some questions on Methylphenidates for ninth grade health in Pennsylvania, particularlly focusing on the ADHD supportive drug, Concerta, and its incredibly quick-rising popularity as a recreational drug among the teen and adult audiences.

1. If you were to take three white 36 mg/g (I can't remember what the teacher said, I think it's mg), what kind of feelings/symptoms would I encounter?

2. Why do some people use it recreationally?

3. Is there a possibility of a nation/statewide law preventing the use of it?

4. Of the people who use it, what percentage develop an addiction? Is there even any kind of physical dependency for Concerta?

5. About how many of the above stated Concerta pills would it take for the average person to overdose?

6. If there is an psychological effect, how long does it last for one pill? Two pills? Three?

When, and if you answer these questions, please put the number of the question that the answers corresponds with.

Thank you, very much!!
