Uruguay has become the first country to fully legalize the sale and cultivation of recreational marijuana. The law, which was initially passed in 2013, finally went into effect on Wednesday.

The weed, however, isn’t very strong. Uruguay is offering two different strains, dubbed Alpha 1 and Beta 1. Both have a THC content of just 2 percent, much lower than the levels found in legal recreational weed in the U.S. In Colorado, recreational marijuana contains an average of 18.7 percent THC; in Washington state, it’s 16 percent. The Uruguayan government is also putting a strict quota in place, limiting the amount of weed a customer can purchase.
