Age Verification

1Account Age Verification

To purchase products from our store, you must be over the age of 18. To ensure you're over the age of 18, we run an effective and monitored age verification process, provided by 1Account. We do not sell age restricted products to persons under the age of 18. By purchasing age restricted products, you hereby consent to the processing of your personal data for age verification purposes.

Why Do We Need To Verify Your Age?

The law in the United Kingdom states that tobacco and nicotine inhalation products cannot be sold to persons under the age of 18. To ensure that we're compliant with the law, we have to carry out some form of age check and we can only do this during the checkout process. Much like buying from a physical location, you would need to provide identification if you looked under age, but because we cannot see who you are, we have to ID everyone.

If you do not verify your age, we cannot legally dispatch your order, so after 5 days (this is when the age verification link expires) we will refund your order, unless requested beforehand.
