The world has seen an increase in the use of cannabis products during recent years, but the laws regarding home cultivation are somewhat stricter than you might expect. Less than 40 states have legalized medicinal cannabis, and about half of them allow home-growing ―while in 16 states it is still considered illegal. 

It’s very likely that as the demand continues to increase, more states will allow homegrown cannabis for personal use. 

Let’s look over the laws according to each state as it stand

  • New Hampshire
  • New Jersey
