Pot Goes Mainstream: At Least 1 to 1.5 Million Americans are Legal Medical Marijuana Patients

 We don’t know his or her name, but somewhere in one of sixteen states and the District of Columbia is America’s 1,000,000th legal medical marijuana patient. We estimate the United States reached the million-patients mark sometime between the beginning of the year to when Arizona began issuing patient registry identification cards online in April 2011.

Between one to one-and-a-half million people are legally authorized by their state to use marijuana in the United States, according to data compiled by NORML from state medical marijuana registries and patient estimates.  Assuming usage of one-half to one gram of cannabis medicine per day per patient and an average retail price of $320 per ounce, these legal consumers represent a $2.3 to $6.2 billion dollar market annually.

Based on state medical marijuana laws, the amounts of cannabis these legal marijuana users are entitled to possess means there is between 566 – 803 thousand pounds of legal usable cannabis allowed under state law in America.  These patients are allowed to cultivate between 17 – 24 million legal cannabis plants.  There may possibly be more, as California and New Mexico “limits” may be exceeded with doctor’s permission and some California counties explicitly allow greater amounts, so there may be as much as 1 million pounds of state-legal cannabis allowed under state law in America.

Yet after fifteen years, one million patients, and a million pounds of legal marijuana, few if any of the dire predictions by opponents of medical marijuana have come to fruition.  Medical marijuana states like Oregon are experiencing their lowest-ever rates of workplace fatalities, injuries, and accidents.  States like Colorado are experiencing their lowest rates in three decades of fatal crashes per million miles driven.  In medical marijuana states for which we have data (through Michigan in 2008), use by minor teenagers is down in all but Maine and down by at least 10% in states with the greatest proportion of their population using medical cannabis.

Fourteen of the seventeen medical marijuana jurisdictions have mandatory registries while two (California and Colorado) offer optional registries and one (Washington) has no registry system.  Estimating California’s patient numbers is hampered by its registry system being on a county-by-county basis.  California NORML’s Dale Gieringer estimates between 2% – 3% of the state’s population are holding medical marijuana recommendations – meaning possibly over one million medical marijuana patients in California alone.

California’s patient population can be estimated from data from other medical marijuana states where patients are required to register, shown in the table below. The top two of these are Colorado and Montana, which, like California, have a well developed network of cannabis clinics and dispensaries, and which report usage rates of 2.5% and 3.0%, respectively. Other states, where medical marijuana is less developed, report lower rates of 1% and less. However, California is likely to be on the high side because it has the oldest and most liberal law in the nation. Significantly, California is the only state that permits marijuana to be used for any condition for which it provides relief – in particular, psychiatric disorders, such as PTSD, bipolar disorder, ADD, anxiety and depression, which account for some 20%-25% of the total patient population. Adjusting for this, usage in California could be as much as 25% to 33% higher than in Colorado and Montana, which would put it well over 3% of the population (1,125,000).
