Cannabis.... well many years ago as a full time track rider and a very busy one at that. I fractured my neck in a spectacular fall at the gap at Avondale. I was one of the lucky ones and walked away from that fall.... but for the next three years I suffered from numbness and muscle aches and pain down the right side of my arm and body, YES I continued to ride track work and YES I began having a tote of cannabis by pipe just before I would go to bed at night, it was the only pain and nerve reliever that worked so I could sleep all night.
My rule with this drug was not to use before nightfall and it was only one or at most two totes... just to release the pain so I could sleep. The drugs the doctors offered me were very powerful and addictive and i refused to take the prescriptions.
These days I hav no need to use this drug and haven't for many years now.
I do share concern regarding riders turning up at the track totally stoned of their faces.
I do believe in using this drug for certain pain relief and illnesses.
