How do you store LSD and how long will it keep?

Answer 1

LSD is a sensitive chemical so certain measures must be taken to store it effectively. The most important variables are reducing maintaining light and airflow. You should ideally use a dark amber glass container stored in a cool place. If you can't get glass using a plastic bag in conjunction with tinfoil (i.e blotter tab wrapped in tinfoil inside a plastic bag) is viable.

LSD degrades slightly at room temperature so it's a good idea to keep it in a refrigerator or freezer.

Under ideal conditions LSD will last for many years. Foil/plastic in a freezer will maintain it for at least a few years.
