Laws in England may be different from your home country’s.
This especially applies to tobacco, alcohol and self defence sprays.
Tobacco and Drugs
You must not carry drugs with you of any kind (unless prescribed by a doctor), or use any illegal drugs including LSD or amphetamines. You must be 18 to buy and smoke cigarettes of tobacco.
Alcohol
You must be 18 to buy alcohol – most English pubs don’t welcome under 18’s.
Weapons
It is illegal to carry weapons, including self-defence sprays.
