There are plenty of vaccine incentives being offered around the world in order to get doses into people's arms, and Washington state's latest perk program is good for anybody who's a fan of going green.

From June 7 to July 12, state-licensed cannabis retailers in Washington can get a temporary allowance to provide one free joint to adults who get a first or second dose at an in-store COVID-19 vaccine clinic.

These cannabis retailers can only give out one pre-rolled joint per person and only for people who are 21 years of age or older.

There is a catch, though. The free joints have to be given out to people during their visit to the in-store clinic to get a dose, so if you don't take one while you're at the clinic getting a vaccine, you can't come back later and claim it.

Other states are also offering perks to try and get people vaccinated including huge lottery prizes in California and Ohio and free tickets to baseball games in New York.
