5mg is one of the lowest e-liquid strengths on the market, and is the lowest nic salt strength people use before moving onto 0mg juice or quitting altogether. When written as a nicotine percentage, 5mg translates to 0.5%. This is a low strength, especially considering most people using disposable vapes are vaping 2% (20mg) of nicotine, 4x the amount of a 5mg juice. 5mg is not a lot of nicotine and is perfect for people who were light smokers or are looking to reduce their nicotine from higher strength vape juice.
No, 5mg is equal to 0.5% nicotine and 50mg is equal to 5%. 50mg is an insanely strong amount of nicotine, it legally cannot be sold in the UK. The highest amount of nicotine that can be purchased legally in the UK is 20mg (2%). 5mg means that there is 5mg of nicotine per ml of vape juice, or 0.5% of the liquid is nicotine. A 50mg juice would have 50mg of nicotine per ml, and 50% of the bottle is nicotine. If you're unsure always check the mg/ml and the percentage stated on the bottle.
Yes, 5mg nicotine salts are suitable for beginners as they're low-strength and smooth on the throat. 5mg is recommended for light cigarette smokers or people that already vape who are looking to reduce their nicotine intake gradually. 5mg nicotine salts have a lot more flavour than their stronger counterparts due to less dilation of flavour. If you're a beginner vaper who owns a starter kit and you're looking to start your vaping journey using 5mg nic salts, make sure that it's not too weak for you and offers a strong enough throat hit.
