Impacts of acidic water and Soil acidification on plants could be minor or in most cases major. In minor cases which do not result in fatality of plant life include; less-sensitive plants to acidic conditions and or less potent acid rain. Also in minor cases the plant will eventually die due to the acidic water lowering the plants natural pH.
Adverse effects may be indirectly related to acid rain, like the acid's effects on soil (see above) or high concentration of gaseous precursors to acid rain. High altitude forests are especially vulnerable as they are often surrounded by clouds and fog which are more acidic than rain. [83] Plants are capable of adapting to acid rain.
A "bad trip" is a highly unpleasant psychedelic experience. [8] [25] A bad trip on psilocybin, for instance, often features intense anxiety, confusion, agitation, or even psychotic episodes. [26] Bad trips can be connected to the anxious ego-dissolution (AED) dimension of the APZ questionnaire used in research on psychedelic experiences. [8]
Many of these plants are used intentionally as psychoactive drugs, for medicinal, religious, and/or recreational purposes. Some have been used ritually as entheogens for millennia. [1] [2] The plants are listed according to the specific psychoactive chemical substances they contain; many contain multiple known psychoactive compounds.
Substance effect class Notes 2C-B: 4-Bromo-2,5-dimethoxyphenylethanamine Psychedelic: There are claims that 2C-B is used as entheogen by the Sangoma, Nyanga, and Amagqirha people over their traditional plants. It is referred to as Ubulawu Nomathotholo, which roughly translates to "Medicine of the Singing Ancestors".
However, plants must maintain a neutral charge in their roots. In order to compensate for the extra positive charge, they will release H + ions from the root. Some plants also exude organic acids into the soil to acidify the zone around their roots to help solubilize metal nutrients that are insoluble at neutral pH, such as iron (Fe).
Acid growth refers to the ability of plant cells and plant cell walls to elongate or expand quickly at low (acidic) pH. The cell wall needs to be modified in order to maintain the turgor pressure. This modification is controlled by plant hormones like auxin. Auxin also controls the expression of some cell wall genes. [1]
The harmala alkaloids are not especially psychedelic, even at higher dosages, when hypnagogic visions, alongside vomiting and diarrhea, become the main effect. Harmala alkaloids are also found in many other plants, such as Passiflora. The leaves of P. incarnata have been reported variously to give 0.005%, 0.12%, and 0% harmala alkaloids. [6]
