The best strength for a nic salt ultimately depends on you and how much you vape / smoke. However, the majority of new vapers start on 20mg (2%). This is because its the most similar to smoking cigarettes. If you've ever had a disposable vape that contains nicotine, you've more than likely vaped 20mg nicotine. 2% is the highest nicotine strength legally allowed in the UK. It's best suited to people who were heavy smokers or heavy users of disposable vapes. Like the nic salts featured in this list, the majority of nic salts are available in more than just one nicotine strength. Most brands offer 10mg (1%) and sometimes 5mg (0.5%). These strengths are perfect for gradually cutting down your nicotine intake. Most people find that when they move away from disposables onto a higher-powered pod kit, 10mg is usually enough to keep the nicotine cravings as bay.
