Relatively few phytochemical studies have been conducted on very old samples of Cannabis sativa L., particularly leaf and stem material [1–4]. At least one article  has shown that the fluid extract of marihuana is stable for as long as 40 years. A more recent article  reports on the stability of cannabinoids in stored plant material at different temperatures.
