Meet the e-cigarette regulation proposal by the Health Ministry of Finland

Translations for the rest is underway, but here are the directly user
related bits.
The justification is mostly based on harmonization restrictions
with cigarettes, protecting the children, protecting the public from
exposure and the "national" plan of getting rid of nicotine product 
use in Finland by 2030.
No evidence was cited.

Electronic cigarette is defined as a product that CAN be used to consume nicotine containing vapor via a mouthpiece, along with any parts of such a product.

Restrictions:

- Selling or otherwise hand over electronic cigarettes or liquids to persons below 18 years of age

- A sales person must be present when an electronic cigarette or liquid is handed/given/sold to a customer

- Automatic vendors not allowed

- Consumers cannot acquire or receive electronic cigarettes or liquids via mail or other similar means from outside Finland

- Can’t be sold or otherwise handed over via any kind of distance means, phone internet mail-order etc

- Product must release consistent dose under normal operating conditions (included provisions for variable wattage devices and puff length, so basically I think most devices can manage this)

- Electronic cigarettes and liquid containers must be protected from children, misuse, breakage and leakage and must have a leak-proof filling system

- Container maximum size 10ml, nic level 20mg/ml

- Devices can only ever fit a maximum of 2ml liquid, regardless of type

- Liquids cannot have any flavors. Flavoring products also cannot be sold or otherwise handed over together with liquids or if the packaging suggest they are intended for e-liquids and cannot be placed in close proximity of e-liquids in stores.

- Import restriction is set at 10ml for liquids that do not have warning labels in finnish and swedish, this is based on an estimate that the liquid is equivalent to 200 cigarettes. No mention of nicotine strength.

- Selling liquids requires a permit, costing 500 euros a year.

- Marketing banned

- Electronic cigarettes and liquids and their brands cannot be displayed in retail stores. A dedicated store can display their products provided the space has a separate entrance and products are not visible from the outside.
