THC Lean is a cannabis-infused syrup that’s perfect for mixing with drinks. As the cannabinoids are delivered in liquid form, the effects occur a bit more quickly than your average edibles. It’s made from Decarboxylated cannabis / cannabis extract is mixed with syrup which is then infused with the THC. Shatter, budder or wax is great for this because it dissolves smoothly without leaving plant material/residue.Reminding us a little of ‘Purple Drank’ that rappers talk about in the US, the notable difference with that instead of Codeine the effect comes from THC. Some people do add Codeine to their Lean mixture, or use Codeine syrup, but we find the effects are perfect just using THC.
