ohhhh I find thats interesting. I'm not a pot smoker etc etc blah blah blah... BUT I know that I needed something that would disassociate my mind from things to get over the panic I was feeling at one point. I was all for a drug free natural labour but at one point my mind went *CRAP!!!!* so I asked for pethadine and that helped me get through everything to achieve the birth I wanted in the end.
