One of the best treatments for constipation is to go natural. Many natural laxatives can take care of the problem. Some are used to spur bowel movement on, and others loosen or soften fecal matter. Medical marijuana can treat digestive disorders, including constipation. Ingesting whole cannabis extract will relax your bowels, just as smoking or vaporizing will do. Using fresh marijuana leaves in your breakfast smoothie will also help a constipation problem. Cannabinoids are anti-spasmodic and sedate where there are pain and inflammation. The relaxing effect of THC and CBD is also helpful in dealing with constipation.
