Chemdawg first appeared in Montana in the 1980s, and it continues to be praised in the medical marijuana community for inducing a heavy, relaxed feeling that works well for patients with depression and PTSD. The reason why Chemdawg is so effective at perking up depressed or traumatized patients is because of its substantial THC percentage and above average CBC levels. This one-two combination is a surefire way to help put patients' minds at ease. Glaucoma patients will also be able to lower their ocular pressure thanks to this strain's THC, CBG, and CBN content. Beginners should always be aware that Chemdawg is typically a potent strain, and is best reserved for patients who medicate frequently.
