Comparing THC Administration Method with Absorption and THC Content

Introduction

The method of administration of THC (Tetrahydrocannabinol) can significantly affect its absorption rate, onset, and overall bioavailability. Various methods—ranging from smoking to edibles to topical applications—each come with their unique pharmacokinetic profiles. This article aims to provide an overview of the timing of absorption and other influential factors like environment, stomach content, and recent physical activity.

Comparison Table

Method of Administration	Timing of Absorption	Impacted by Environment	Impacted by Food	Impacted by Metabolism	Impacted by Activity Level
Joint	1-3 minutes	Moderate	Low	High	Moderate
Pipe/Bowl	1-3 minutes	Moderate	Low	High	Moderate
Bong	1-3 minutes	Moderate	Low	High	Moderate
Vaporizer (Outlet)	1-5 minutes	Low	Low	Moderate	Low
Vaporizer (Handheld)	1-5 minutes	Low	Low	Moderate	Low
Edibles	30-120 minutes	Low	High	High	Moderate
Topical	N/A	Low	N/A	Low	N/A
Buccal	20-40 minutes	Low	Moderate	Moderate	Low
Suppository	15-45 minutes	Low	Low	Moderate	Low
Transdermal	30-60 minutes	Low	Low	Moderate	Low

Discussion of Methods

Inhaled Methods (Joint, Pipe/Bowl, Bong)

Rapid absorption with onset within minutes, usually less affected by the environment but significantly influenced by metabolic rate (Huestis, 2007).

Vaporizers

Both outlet and handheld vaporizers have a quick onset of effects, are less influenced by the environment and food content, but metabolism plays a moderate role (Gieringer et al., 2004).

Edibles

Slowest onset due to first-pass metabolism, highly impacted by food content in the stomach and metabolic rate (Grotenhermen, 2003).

Topical

Generally not absorbed into the bloodstream, least affected by metabolism, activity level, and food content (Stinchcomb et al., 2004).

Buccal

Moderate absorption rate and is mildly influenced by metabolism, food content, and activity level (Pavlovic et al., 2018).

Suppository

Quick absorption and low influence by environmental factors, food content, and activity level (Russo, 2018).

Transdermal

Steady absorption and minimally affected by most external and internal factors (Paudel et al., 2010).

Special Considerations and Warnings

Patients with cardiovascular disorders, liver or kidney issues, psychiatric illnesses, or those who are pregnant should consult with Dr. Caplan at CED Clinic for specialized, evidence-based treatment plans.
