Why the Same THC Dose Behaves Differently at 30 and at 70
Cannabis pharmacokinetics in older adults rests on a thinner evidence base than most clinical discussion suggests, with the only controlled trial in adults over 65 enrolling twelve people. Route of administration shifts the balance between THC and its…
What Actually Reaches the Bloodstream: Measured Cannabinoid Exposure From Inhaled, Oral, and Topical Products
How much THC gets into your blood is decided by the application method, and controlled studies have measured inhaled, oral, and topical routes in the same laboratory conditions. Commercial topicals delivered detectable cannabidiol and no detectable THC…
Fed or Fasted: When Cannabinoid Levels Peak, and How the THC to CBD Balance Shifts
Taking cannabis with food raises how much reaches the bloodstream and separately moves when the level peaks. Oral THC shifts from a peak under two hours fasted to between five and eight hours fed. The one trial that measured both cannabinoids together…
How You Take Cannabis Changes What It Does: A Route by Route Reference
Cannabis routes of administration differ in onset, duration, how much of a dose reaches the bloodstream, and which active metabolites the body produces. Controlled studies place inhaled onset in minutes and oral onset at 30 to 90 minutes, and show that…
Why the Same Edible Behaves Differently on Different Days
Cannabis edible absorption varies several-fold from one evening to the next, and controlled trials have measured which variables are responsible. Dietary fat is the largest lever, raising peak concentration and total exposure substantially while delaying…
Taking Cannabis on an Empty Stomach Lowers Blood Levels: What the Food Effect Trials Show
This page previously claimed that taking cannabis on an empty stomach roughly doubles peak THC blood levels, and that claim has been removed as unsupported. Controlled human food effect trials show the opposite direction: a high fat meal raised peak…
Cannabis Use Is Soaring Among Older Adults—and Clinicians Are Largely Unprepared
Cannabis use older adults risks are rising as usage grows tenfold in two decades. This 2025 evidence review highlights pharmacokinetic changes and drug interactions unique to seniors. Clinicians face challenges guiding cannabis use with limited…

Understanding THC Beverages: Clinical Insights and Pharmacokinetics
THC beverages pharmacokinetics clinical insights reveal faster onset and unique dosing considerations compared to traditional edibles. Understanding these factors is crucial for patient safety and effective clinical guidance. This knowledge helps…
A marijuana breathalyzer is one step closer to coming to market | The Independent
The breath-based detection method cannabis technology is advancing towards real-time impairment assessment. Current cannabis impairment detection relies on less accurate blood or urine tests. This new method could improve clinical and law enforcement…
