Further Research Findings

I found two research articles I feel approach this topic nicely:

Read, J.P & Richard A. Brown. (2003). "The Role of Physical Exercise in Alcoholism Treatment and Recovery". Professional Psychology: Research and Practice American Vol. 34, No. 1, 49-56.

and

Vuchowski, M. S. et al. (March 2011). "Aerobic Exercise Training Reduces Cannabis Craving and Use in Non-Treatment Seeking Cannabis-Dependent Adults." PLosOne Vol. 6 Issue 3.
