Its neurotoxicity is very variable, and is increased by a number of factors, including crowded conditions and increased ambient temperature. The effects of such factors are increasingly important, with the widespread use of these stimulants at nightclubs and 'raves'. Here, we compared the effect of another dominant feature of nightclubs, continuous loud noise, on the toxicity of METH in mice. We found that mice exposed to loud music exhibited longer lasting stereotypy, an altered place preference in the open field and had more seizures than mice given METH in a quiet setting or when exposed to loud white noise. A greater increase in reactive gliosis was also seen after exposure to METH and loud music. Thus, METH appears to be more toxic when taken while exposed to loud music. © 2001 Lippincott Williams & Wilkins, Inc.
