A slang term for Thailand’s street version of “lean.” Unlike the American version that mixes codeine cough syrup with soda and candy, Thai Lean is almost always just kratom tea (namtom) combined with diphenhydramine (Benadryl) syrup or crushed tablets, sometimes with tramadol or other cheap medicines. While soda might be added occasionally to mask the bitterness The effect is a heavy, sedating high layered over kratom’s stimulant base, but it’s unpredictable and carries significant health risks.
