Each medical cannabis market is different, based on factors including the number of qualifying conditions, number of dispensaries, and overall rates of cannabis use in the state. One way to estimate the potential size of Pennsylvania’s medical cannabis market is by analyzing patient participation rates in other states. Among states that officially track their medical cannabis patients, Colorado has the highest patient count with nearly 106,000 patients. This is equal to 2.9% of the state’s adult population. Comparatively, Nevada has the smallest patient population ratio at less than one percent, equaling 16,000 patients. If Pennsylvania’s market grows to the size of Colorado’s the state will have nearly 248,000 patients, compared to 71,000 patients if the market resembles Nevada’s model.
