During investigations into using transcranial brain stimulation (TMS) to treat cocaine abuse, two projects take diverging paths. One researcher moves to the next stage, while another is forced to cut his trial short.
Two researchers share their reasons for researching transcranial magnetic stimulation (TMS) for treating cocaine addiction, and describe challenges to moving forward this potentially promising therapy.
Exposing rats to THC increases the likelihood that the animals will later self-administer nicotine. THC-exposed rats are also willing to work harder to obtain nicotine. When extrapolated to people, the findings suggest that THC’s pharmacological impact on the brain may make a person who uses marijuana more vulnerable to developing nicotine addiction, an underappreciated health consequence of marijuana use.
