My buddy has Crohn's, and is on all kinds of pharmaceuticals. Especially for pain.
mmj USED to help stimulate his appetite, take the "edge" off the op*ate effects, and he could gain some weight.
then... they pissed him, and told him if he pissed positive again, he wouldn't be able to get his pain meds.
now he only puts weight on when his
pr*dnisone cycle comes around.
i told him to move to michigan. those mmj folks really have their stuff together.
personally, i prescribe to an old indica strain that KILLS my gut pain within 5-15 seconds of first exhale. this strain has been in my family for years... way b4 all these fancy names. but i think indicas are a good starting point for you.
i am completely op*ate and gluten free.
