I dont really understand what she meant and she also said it causes addiction as well! i dont get how this works! please can someone explain it to me in full detail????

First of all are you aware of the nervous system arcs with the different nurones (such as motor) and the diagram of a synapse? Basically part A of a synapse (which will be the tip of a nurone that is passing the electrical message to another) will release certain chemicals that will convey a message and also effect a persons mood. The smoking or taking of certain drugs causes the Nurones to release masses of these 'feel good' nurones across the synapse and therefore leads the taker to feeling amazing and happy. This is sometimes what leads to the addiction as the concious mind always wants to feel happy and good about its self and will do anything to feel that way, hence the addictions. However, this doesn't sound very bad but the constent hight consentration of these chemicals has several downfalls which is why drugs are dangerous to take. As you can see on the diagram there are little balls floating in the space between the two nurones, these are the chemicals. You will also note that on nurones B (The reciever of the message) there are little cup like pincers. These are where the chemicals go and are interpreted as a message or feeling. If these pincers are constantly being used as there is a high consentration of chemicals then they can deform and become useless, this is dangerous as it means that you can no longer convey messages as fast as you previously could, if at all in extreme cases. Also, the constant use of these 'feel good' chemicals leads to their weakening. They no longer give quite as strong a feeling as the synapse becomes accustomed to using them and they no longer have quite such a big effect. This is why certain illigal drug takers may try to find stronger or more leathal drugs, so that they can obtain a stronger release of these chemicals and therefore a better 'buzz'. I hope that covered most of what you are wondering about and I can go into more depth if you wish but I feel that this is already too long! Glad to help!

I know that if you smoke Ecstasy it blokes a part in your synapses which reabsorbs the serotonin. Serotonin is a chemical which makes you happy. And if it isn't reabsorbed is makes someone fell really happy. Hope this helps.
