Weed and hashish are tolerated in the Netherlands. They are narcotics that have a high risk of addiction. That is why it is important to deal with cannabis responsibly. A first step in that is knowing what you smoke. It is important to know what different species do with your body. First, there is the difference between Sativa and Indica. On the site of cnnbs.nl it is very well explained:
The effect of different types of weed
In this article we discuss the typical effects of indicas, sativas, hybrids, CBD weed and foreign hashish.
Indica, sativa and hybrid weed types
The effect of weed varies by species. This has to do with different cannabinoid profiles, or the many active substances that cannabis can contain. CBD and THC are two well-known cannabinoids but cannabis contains many more cannabinoids and other substances such as terpenes, all of which have a greater or lesser effect on the effect you experience.
Unfortunately, in most coffee shops you don't get a test report with all the different cannabinoids. It is also impossible to know about the influence of this cocktail on active substances. However, there is something to be said about the general differences between the main weed types indica and sativa and crosses between them (hybrids).
Indica weeds and indica dominant hybrids generally give a heavier and lomer stoned effect. The effects are mainly physical, and less psychological than sativa weed types. Indicas usually work well against pain and have a numbing effect on the body. Indica's are ideally suited to help with a good night's sleep and are therefore ideal types of weed to enjoy in the evening, when there are no more activities on the schedule.
Sativas are also known for their energetic effect on the mind. The cerebral energetic high stimulates creativity and energizes. This makes sativas more suitable for smoking during the day, or to enjoy when you still have some (creative and social) activities to do. The especially mental effect of a sativa can cause anxious or paranoid feelings, in people who have a predisposition to it.
Hybrid weed types are crosses between indicas and sativas, and thus have both indica and sativa influences. The effect is between that of an indica and a sativa, and depends to a large extent on the percentage of indica or sativa genes. Sativa dominant weed species will have a more spiritual, energetic effect, and indica dominant weed species give more of a numbing effect.
Most of the pots you will encounter in the coffee shop or at seed companies are crossbreeds. In good coffee shops they can advise you on the effect of a species.
CBD weed and foreign hashish
CBD weed types are actually a case in point. By CBD species we mean weed species that contain a high percentage of CBD (cannabidiol). These can be both indicas and sativas as hybrids. Common (non-CBD) weed species hardly contain CBD but CBD species do. CBD is not psychoactive. Some CBD weed species contain almost no THC while others contain about the same amount of THC as CBD.
Because CBD is a counterpart (antagonist) of THC, it dampens the effect of THC. At high doses it gives a sedative, calming and soothing effect.
Hashish, especially foreign hashish species, also have an effect that is often similar to that of CBD species. This is due to the way of drying and production abroad; the weed used to make the hash is often dried in the open air, turning some of the THC into CBD and oils and terpenes partially disappear.
It is therefore worth not just smoking what you are offered, but consciously choosing a particular species. The way of smoking also affects the effect. For example, in a joint, tobacco usually enhances the heavy languid feeling of indicas. To best notice the effect of pure weed, evaporation is probably the best and most healthy way.
