I like the Spikers cannabis cocktail 100mg mixer. You just mix the concentrate with club soda to your liking. Best of all, it looks like a cocktail in your favorite stemware!
@2 actually that's one of the more interesting options, there's a product called Potshotz which is essentially a powdered cannabis extract, activated and ready to add to any beverage. It is sugar free and has almost no flavor -- it can only be tasted when added to water, basically. It can be purchased all over the state at licensed shops, including OZ. in Fremont (disclaimer: my wife and I are the owners). Hope this helps, it's a cool product!
