As liquid and powder-based CBD beverage enhancers have become more common in recent years, it figures that THC wouldn’t be too far behind. This month sees the launch of ALT (Advanced Liquid Technology), a sugar-free liquid available in 5mg and 10mg formats which is designed to be added to any drink for easy micro-dosing. The product is sold in select dispensaries in California in 5-packs of 5mg ($28) or 10mg ($38) vials, or in single packs for $6 and $8, respectively.
