Does rapid cycling in bipolar ppl lead too drug use or does drug(amphetamines)use cause rapid cycling cause? or can amphedimienes help cycling?

Much worse: You asked an earlier question about rapid cycling bipolar illness, indicating your family is concerned enough about you to suggest hospitalization. This illness may indeed lead to substance abuse, and amphetamines can definitely destabilize your mood (worsening the rapid cycling). Amphetamines do not help bipolar d/o -- they can worsen it. Please stop, listen to your family, and get help.
