France

Using or possessing drugs including cannabis is illegal in France even in private, and police can issue an immediate flat-rate fine of €200.

The €200 fine rises to €450 if unpaid, goes on your criminal record, and serious cases carry up to 1 year in prison and a €3,750 fine.

You may bring personal medication into France only in quantities matching your prescription (up to 3 months for ordinary drugs), and narcotic or psychotropic medicines require the original prescription and roughly a 1-month limit.

Original doctor's prescription is mandatory for narcotic/psychotropic medicines; for narcotics, an ANSM transport certificate may be required by the destination country.

You must declare cash, gold or equivalent of €10,000 or more to customs when entering or leaving France (or the EU).

Non-declaration can mean a fine of up to 50% of the sum and temporary seizure of the money.

France's drink-drive limit is 0.5 g of alcohol per litre of blood (0.25 mg/L of breath), dropping to 0.2 g/L for novice drivers with a probationary licence.

From 0.5 g/L: fine up to €750 and loss of 6 licence points; 0.8 g/L or more is a criminal offence with up to €9,000 fine and 3 years in prison.

In France you must give way to traffic approaching from your right at most intersections and roundabouts, and driving under the influence of drugs or alcohol can lead to immediate arrest.

Driving under the influence may result in immediate arrest and detention.

French law restricts drone use and photography/video of sensitive sites — airports, military bases, prisons, nuclear plants — and large gatherings such as concerts and parades.

Up to 75,000 euro fine or 1-year imprisonment

There are no legal restrictions on same-sex relationships or the organization of events in France.
