There are a lot of cannabis strains available but there are only a handful of classics that consumers come back to again and again. Here are 5 of the world's best selling cannabis strains:

1. White Widow

This strain has been sitting on 'best strains' lists for a long time now, with its signature white crystals and heady high -what's not to love?

2. Green Crack

Snoop Dogg was the man who named this strain, and anything Uncle Snoop approves must be good, right? This high-energy sativa with its tropical fruit flavors is perfect for a nice afternoon pick-me-up.

3. Girl Scout Cookies

Girl Scout Cookies are just as sweet as their sugary namesake. Prepare for a cerebral high and full-body relaxation when you light up this stuff.

4. Gorilla Glue #4

Named for it's ability to glue you to your chair (this stuff is strong), Gorilla Glue #4 has steadily been scooping up market share across the legal US. Last year it was also embroiled in a legal battle with its namesake company, with the two eventually reaching a settlement.

5. Skywalker OG

The force is strong with this one. With high levels of THC and a reputation for putting people to sleep, Skywalker OG has become a bedtime staple. Unfortunately, this stuff is harder to come by these days as Disney has been cracking down on Star Wars related cannabis products.
