How does cannabis benefit workouts!?!

 During anaerobic and aerobic activities:

  1. After workout to support recovery
  2. Before running to find the Zone
  3. Before lifting as analgesic

Because the federal government has abdicated its public health responsibilities (in response to money from the alcohol, tobacco, and pharma lobbyists), research into the health benefits of cannabis has been severely restricted and nearly eliminated.
Therefore, most articles are based on anecdotal evidence.
