Transdermal administration involves delivering drugs like THC and CBD through the skin for systemic absorption rather than localized topical effects. Transdermal products are specifically engineered to permeate outer skin layers and enter the bloodstream. Options include adhesive patches, fast-acting gels, micro-dosed sprays, and time-release creams. Unlike traditional topicals, transdermals provide whole-body cannabis effects without ingesting or inhaling. However, the formulas require specialized technology to enable epidermal penetration. When applied correctly, transdermal patches provide long-lasting relief without smoking or vaping. Sprays and creams act faster but require reapplication.
