As an old farm boy, it has always seemed strange to me that most states, and the federal government, treat someone who grows a few marijuana plants for personal use as a more serious offender than someone who buys cannabis from the black market. In practice, by penalizing personal cultivation, the government encourages a thriving black market with absolutely no controls over age, potency or purity. At least if one grows their own marijuana, they can be assured it includes no pesticide residue or other harmful additives. This is an arbitrary policy that has absolutely no basis in public safety.
But marijuana prohibition has never been a rational policy, and this bias against home cultivation is just another example of that principle.
At NORML, we have always supported the right of individuals to grow their own marijuana, as a logical option compared to purchasing it from licensed dispensaries. On one hand, growing your own just makes common sense. We can brew up to 100 gallons of home-brew beer in our basements under current law, even if very few Americans actually make their own beer. The same should be true for cultivating our own marijuana.
