Sex drug could be made class A

Ministers are to consider tightening the law on a highly addictive drug that lowers sexual inhibitions.

Methamphetamine, also known as crystal meth or Tina, could be reclassified as a category A substance amid fears that its use is increasing in Britain.

Researchers claimed today that up to one in five gay men in London uses methamphetamine. In the US, its use has spread from the gay community to the wider population.

One former addict said: "It rewires your brain and it controls your thoughts. Everything in your world when you are on crystal revolves around Tina."

The advisory committee on the misuse of drugs has been asked to review the law on the substance, which is currently category B.

A working group is investigating and the committee is expected to report back in November.
