i just found this when looking for concerta info:

https://www.concerta.net/adult/free-concerta-coupon.html

obviously, you can receive a free concerta trial, but only in the USA. :(
so, while i cant try this, i thought i'd share... maybe it helps some people in the USA who are concerned about the costs but would like to try concerta nevertheless.

you're obviously giving away some info about yourself there, so up to you to decide whether you want to do that or not...

i mailed them and got a prompt response; this voucher is definitely not available in germany, and thats because the law is different here. it has to do with methylphenidate counting like a drug same as opiate, cocaine, morphine, whatever here - you need a special prescription for it, you need a permit to carry it when you travel, etc. - and thus, doctors or patients cannot receive free samples. this is, for some reason, different with US laws. oh well, shame.
