Summary
One average areca nut (~2 g) contains ~5-8 mg arecoline. Calcium hydroxide or slaked lime is traditionally added to basify saliva and improve buccal absorption, but greatly increases oral carcinogen formation. Chronic areca nut use is classified as a Group 1 carcinogen by IARC with strong evidence for oral cancer, submucous fibrosis, and systemic health effects.
Dose Information
Dose basis. Buccal exposure from betel quid is highly variable across nuts and preparations; pH elevation with slaked lime increases local absorption but also causes chronic mucosal irritation. Doses inferred from chewing reports and vary by nut cultivar and quid composition; start low due to large interindividual variability. Evidence basis: human chewer PK and salivary levels rather than controlled-dose trials. Beware salt-to-base conversion: arecoline HBr MW ≈236.1; freebase MW ≈155.2. 1 mg arecoline HBr ≈0.66 mg arecoline freebase. Dose conservatively if the label does not specify base vs salt. Arecoline base has an unpleasant taste and greater GI upset in some users. (Dose figures and this note are from Drugs.Wiki.)
| ROA | Light | Common | Strong | Heavy |

Add to PsychonautWiki Journal
The PsychonautWiki Journal logging app doesn't include every substance. To track Arecoline there, start adding an ingestion, search for the name, and choose to add it as a custom substance. Paste these values:
Arecoline Source: SubstanceSearch (substancesearch.com) Buccal dose (mg): threshold 2 · light 2-4 · common 4-8 · strong 8-15 · heavy 15+ Oral dose (mg): threshold 2-3 · light 3-6 · common 6-10 · strong 10-15 · heavy 15+ Sublingual dose (mg): threshold 1-2 · light 2-5 · common 5-10 · strong 10-15 · heavy 15+ Vaporized dose (mg): threshold 0.5-1 · light 1-3 · common 3-6 · strong 6-10 · heavy 10+ Buccal duration: peak 12-42m · offset 0.5-1.5h · total 1-2h · after-effects 1-3h Oral duration: onset 15-25m · peak 12-42m · offset 0.5-1.5h · total 1-2h · after-effects 1-3h Sublingual duration: onset 2-5m · peak 12-42m · offset 0.5-1.5h · total 1-2h · after-effects 1-3h Vaporized duration: onset <1-2m · peak 12-42m · offset 0.5-1.5h · total 1-2h · after-effects 1-3h Note: ranges are harm-reduction guidance, not a prescription. Start low, go slow, and test your substances.
Tip: for quicker logging you can also add a Custom Unit in the app, e.g. common dose ~ 6 mg (Buccal).
The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.
Tolerance
Tolerance Decay
Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Tolerance patterns are inferred from habitual quid users (rapid tolerance to salivation and GI effects, less to cardiovascular effects). Data are low quality and largely anecdotal; sustained daily use tends to increase dose frequency due to short duration.
