you can add a little bit of semi liquid tinicture to whole milk and it will bind pretty well. There are also single serve drinks at the dispensary.

Here's a recipe I found for boiling cannabis in milk, which can be added to tea:

Since THC is fat-soluble, the green leaf water infusion does not induce a high, in contrast to its smoked form. There are reports of the effects of the drug being conducive to improving eyesight, though this has not been medically proven. To experience the cannabis tea's mild to potent psychoactivity, take a few grams of the cannabis buds and boil them in a small quantity of milk. Even low fat milk contains enough lipids to activate THC for absorption by the body. Using about 50 ml of low fat milk and 100-150 ml of water, add cannabis as desired. In most cases, this is approximately equal to the quantity used in a joint, i.e. 0.5 g to 1 g; excessive amounts may be undesirable to some users. Boil for between 10 and 15 minutes until the milk becomes an off-tint, brown, khaki colour. In many cases, the taste can be sharp and abrasive. Additionally, the flavonoids will cause a burning sensation in the throat and on the tongue.

This recipe makes enough cannabis tea for the equivalent of one shot, which may be consumed in one or two sessions.
