not normally, maybe from drugs you can, but you will have abnormal withdrawl effects. isnt thats why amphetamines are for and thier pharmalogical deratives. i dont think you can have manic phase with drugs though. because manic phase from bpd, usually comes with severe depression, some people have psychosis, or a co-condition like schizophrenia. i once followed a tuber that had manic and depressive phases, apparently the reason he was barely uploading was his “depression phase” followed by his manic phases, (uploading about his cotent which was very sparingly. after a few years, it was reported in the local news, and through another tuber, he took his own life in his depressive phase. it was mostly about pets/talking,not anything extreme.
