DIY E-Liquid Mixing Guide Ireland
Technical Formulation & VG/PG Ratio Framework
Nicotine is a highly addictive and toxic substance. Use protective gloves when handling nicotine-containing liquids. Avoid skin contact and wash immediately in case of spills. Store all DIY components in locked storage away from children and pets. This guide is intended for adult users (18+) in Ireland.

| Issue | Cause | Fix |
|---|---|---|
| Weak flavour | Low % or no steep | Increase flavour or steep longer |
| Harsh hit | Too much PG/nicotine | Increase VG or lower nicotine |
| Too thick | High VG | Use lower VG or different device |
| Leaking | Liquid too thin | Increase VG slightly |
| Muted flavour | Overflavouring | Reduce flavour % |
