Treacle has a blood pressure monitor.
Tonight, myself and a friend consumed an oral dose of 250mg Mephedrone. Then another 150mg, when we came home. We had also had alcohol and had a small line of speed in the club. We took the reading once we'd been at home and sitting around talking for a while.
Typically in our now druggy drunk state I have forgotten the exact readings for my mate, but his was very high, but he's very sensitive to drugs, his pupils are HUGE.
However, I remember mine was 154/94 but the usual is 120/80, and my heart rate was 128 which is rather high. I had been sitting down for a while when reading was taken.
I preferred taking it orally to snorting it. The come up was smoother and very MDMA like and the high lasted about 3 hours. Really good for dancing! I kept feeling the need to just go off and have a wander on my own without telling my group of mates much more than usual, my mate kept doing this as well I kept bumping into him finding that he was doing the same thing.
Once we started to come down we decided to go on a mission to find some speed in the club.
Obviously this is by no means a scientific conclusion....as other drugs were consumed today and past few days. It does proove though that it really does increase blood pressure and heart rate - a lot! We all knew this anyway!
