I've wondered if the person I know that uses meth heavily purposely sought out a new relationship to trigger the dopamine high associated with it. Maybe not consciously, but the philosophy makes sense to me.

Sex and meth go together quite frequently. Meth causes the body to release a lot more dopamine than it would normally under the usual circumstances (sex, food, exercise, fun). The body, in it's infinite wisdom, soon learns that it doesn't need to release dopamine via the typical channels as the drug will do the work for it. When the drug is stopped, there is a deficit and you are right, it may last upwards of a year or more.
