Ask anyone who takes Hawaii yoga classes for back pain relief, and chances are good that they'll tell you the holistic regimen does wonders for chronic aches. Scientific research certainly "backs" up this idea.
However, treating milder problems (like back aches) with controlled substances is not always warranted. Consider the Highland Health dispensary, which is currently at the center of a legal battle over its placement relative to public institutions in the area. According to The Post, the store has received letters from the U.S. Attorney General's office concerning its proximity to schools.
The news source notes that the dispensary offers yoga classes, hypnotherapy and medical marijuana (which was legalized in the state in 2000), the latter of which is sold only to people with prescriptions, many of whom are seriously ill.
Some studies have also explored the use of medical marijuana to treat post-traumatic stress disorder (PTSD), though NPR reports that the results are unclear. Yoga, on the other hand, has clearly been shown to have a soothing effect for people with PTSD.
Therefore, for individuals who simply have back pain, choosing between holistic exercises and controlled substances is a no-brainer: yoga wins every time.
