In my search for a good infused iced tea, the Black Lemon Iced Tea by Veryvell one finally tastes great! It's different than other iced teas as it's carbonated. So if you're not a fan of carbonated drinks you might not like this one. 

It had a great natural iced tea flavour and it wasn't too sweet. This one will definitely hit the spot during the hot summer months, being that it's pretty low dose, you can drink a few. 

I'm not sure if it's fast-acting however most cannabis beverages are. Fast-acting means this will kick in after about 15 minutes and last only about an hour. So it's a great way to enjoy THC without the commitment.
