Focus suppression can be described as the experience of a decreased ability to selectively concentrate on an aspect of the environment while ignoring other things. It can be best characterized by feelings of intense distractability which can prevent one from focusing on and performing basic tasks that would usually be relatively easy to not get distracted from. This effect will often synergize with other coinciding effects such as motivation suppression, thought deceleration, and sedation.
Focus suppression is an extremely common effect under the influence of heavy dosages of antipsychotics, benzodiazepines, cannabinoids, and hallucinogens. However, it is worth noting that the same stimulant compounds which primarily induce focus enhancement at light to moderate dosages will also often lead into the opposite effect of focus suppression at their heavier dosages.
Compounds which may cause this effect commonly include:
2-Aminoindane, 2-FA, 2-FMA, 2C-B-FLY, 3,4-CTMP, 3-FA, 3-FEA, 3-FMA, 3-FPM, 3-MMC, 4-FA, 4-FMA, 4F-EPH, 4F-MPH, 5-APB, 5-MAPB, 6-APB, 6-APDB, A-PHP, A-PVP, Alprazolam, Amphetamine, Bromo-DragonFLY, Butylone, Caffeine, Clonazolam, Cocaine, Datura, Desoxypipradol, Dichloropane, Diphenhydramine, ETH-CAT, Ethylone, Ethylphenidate, Etizolam, Flubromazepam, Hexedrone, Hexen, Isopropylphenidate, Lisdexamfetamine, MDA, MDAI, MDEA, MDMA, MDPV, Mephedrone, Methamphetamine, Methiopropamine, Methylnaphthidate, Methylone, Methylphenidate, Mexedrone, NEP, NM-2-AI, Nifoxipam, Pentedrone, Prolintane, Propylhexedrine, Selective serotonin reuptake inhibitor, Temazepam
