The term '''duration''' refers to the length of time over which the [[subjective effects]] of a [[psychoactive compound]] manifest themselves. This can be further broken down into a total duration, an onset, a peak, an offset and after effects. Depending upon the substance consumed, each of these occur across different durations of time.

__NOTOC__

These are ~~defined and listed below.~~

'''Duration''' refers to the length of time over which the [[subjective effects]] of a [[psychoactive substance]] manifest themselves.

Duration can be broken down into 6 parts: (1) total duration (2) onset (3) come up (4) peak (5) offset and (6) after effects. Depending upon the substance consumed, each of these occurs in a separate and continuous fashion.

These are catalogued as follows:

===Total===

The total duration of a substance can be defined as the amount of time it takes for the ~~drug's~~ effects to completely wear off into sobriety.

The total duration of a substance can be defined as the amount of time it takes for the effects of a substance to completely wear off into sobriety, starting from the moment the substance is first [[administered]].

===Onset===

The onset can be defined as the ~~duration~~ of ~~time required to reach peak effects~~. This is colloquially known as "coming up."

The onset phase can be defined as the period until the very first changes in perception (i.e. "first alerts") are able to be detected.

===Come up===

The "come up" phase can be defined as the period between the first noticeable changes in perception and the point of highest subjective intensity. This is colloquially known as "coming up."

===Peak===

The peak can be defined as the ~~height~~ of ~~intensity for~~ the substance's effects.

The peak phase can be defined as period of time in which the intensity of the substance's effects are at its height.

===Offset===

The offset can be defined as the amount of time between ~~feeling~~ the ~~full effects~~ and ~~coming down~~ into ~~sobriety~~. This is colloquially ~~known~~ as "coming down."

The offset phase can be defined as the amount of time in between the conclusion of the peak and shifting into a sober state. This is colloquially referred to as "coming down."

===After effects===

The after effects can be defined as any ~~residue~~ effects which may ~~last~~ after the experience ~~itself~~. This is colloquially known as a "hangover" or an "afterglow" ~~depending~~ on the ~~substance~~.

The after effects can be defined as any residual effects which may remain after the experience has reached its conclusion. After effects depend on the substance and usage. This is colloquially known as a "hangover" for negative after effects of substances, such as [[alcohol]], [[cocaine]], and [[MDMA]] or an "afterglow" for describing a typically positive, pleasant effect, typically found in substances such as [[cannabis]], [[LSD]] in low to high doses, and [[ketamine]].

It should be noted that the after effects of the substances listed on this site are not included as part of the total duration.
