Obviously, meth and amphetamine are closely related and are also closely related to MDMA and Ecstasy. However, meth is something I have been trying to learn about recently and it seems quite complicated. Despite being widespread in the US there is very little meth on the streets of the UK with only 17,000 people in the UK known to have taken meth. What are the real differences between meth and amphetamine? Can meth be created from amphetamine? And what are the differences in the dangers of taking them? Are meth and amphetamine really any different?
