text:  Do you believe there may be some synthetic versions of cannabis on the horizon that may not have these negative side effects? Yes, there could very well be. Again, it's an area that is lacking in sufficient research, but it is potentially possible that the cannabinoids could be modified and synthetic cannabinoids could be produced that would limit the side effects that people might experience.
