Hi there. This is my first forum ever. I am a MSc student in the field of addictions and are wanting next year to do my PHD on needle fixation. I personally have been able to get opiate dependent friends into at least three days of withdrawal, yet some of them can not get over the want for the fit and will jump out of my window and inject water, ect. I have searched all available literture on this and have been unable to come up with any answers for this. Any experiences or answers would be much apprieciated. Thank you. Stay safe.
