Tinctures are a very effective administration route that avoids inhalation. Absorption begins in the mucous membranes and continues in the digestive system. The onset of effects is about ten minutes and can last for several hours.
Vaporizing is also a preffered method, but caution should be exercised, as the quality of oils and concentrates is variable, and can contain high levels of solvent and other unwanted chemicals.
