Effective dose: It is the minimum dose or concentration of a drug that produces a biological response in 50% of a population being studied. Median lethal dose: For either drugs or toxins, it is a toxic unit that measures the minimum dose that causes death (lethal dose) in 50% of cases.
The dose of cannabis depends on the individual, the condition being treated, and the ratio of cannabidiol (CBD) to tetrahydrocannabinol (THC) in the cannabis. CBD is a chemical component of cannabis that is not intoxicating and used to treat conditions like epilepsy and other neuropsychiatric disorders.
7-Hydroxycannabidiol (7-OH-CBD) is an active metabolite of cannabidiol, generated in the body from cannabidiol by the action of the enzyme CYP2C19. [1] While methods have been developed for its synthetic production, [2] and measurement of levels in the body following consumption of cannabidiol, [3] its pharmacology has been relatively little studied, though it has been found to possess similar ...
To ensure that the drug taker who has poor absorption is dosed appropriately, the bottom value of the deviation range is employed to represent real bioavailability and to calculate the drug dose needed for the drug taker to achieve systemic concentrations similar to the intravenous formulation. [4]
The EC 50 of a quantal dose response curve represents the concentration of a compound where 50% of the population exhibit a response, [5] after a specified exposure duration. For clarification, a graded dose response curve shows the graded effect of the drug (y axis) over the dose of the drug (x axis) in one or an average of subjects.
[22] [23] It may be supplied as CBD oil containing only CBD as the active ingredient (excluding THC or terpenes), CBD-dominant hemp extract oil, capsules, dried cannabis, or prescription liquid solution. [4] [19] CBD does not have the same psychoactivity as THC, [24] [25] and can modulate the psychoactive effects of THC on the body if both are ...

In toxicology, the median lethal dose, LD 50 (abbreviation for "lethal dose, 50%"), LC 50 (lethal concentration, 50%) or LCt 50 is a toxic unit that measures the lethal dose of a given substance. [1] The value of LD 50 for a substance is the dose required to kill half the members of a tested population after a specified test duration.
