For our chronic opiate patients using marijuana, we give them a choice to either stop the marijuana and we can continue to prescribe, or if they want to try marijuana instead, we will stop prescribing the opiates. So far, a small number have opted to try just using marijuana for pain control instead. The results so far have been mixed: some people think the marijuana is working for them, and some have opted to go back on opiates and stop the marijuana.
Some of our local pain centers are doing small-scale trials of marijuana with opiates, and we await their findings with interest. They tell me that the sticky wicket is the patients are not always buying the same strain/THC concentration of marijuana, which means the studies are poorly controlled for lack of a standardized product, and may make the results anecdotal at best.
