Scientists and researchers alike will say yes. Smokers of marijuana sometimes doubt if it does, because the effects of withdrawl aren't as obvious as opiates, for example. The psychological dependance synptoms are stronger than the physical dependance symptoms, but are there none-the-less.
both
Narcotics cause both mental and physical dependence.Yes
Marijuana can be psychologically addictive (as can practically anything), but there has been no scientific evidence indicating chemical dependence.
No, there is no physical dependence associated with LSD.
You can't actually develop a physical dependence on THC (the active chemical in marijuana). People can only think they need it because they want to justify smoking it.
Yes they can--it's called 'addiction'. They cause a physical dependence too; so do not stop taking them suddenly or you will go through 'cold turkey' withdrawal.
Addiction can be a physical dependence. Physical addiction is not the only form of addiction. There is also psychological addiction, which is also considered addiction. A physical dependence and a psychological dependence often coincide with one another, but they don't always have to. Usually, psychological dependence comes first. One could be addicted to alcohol psychologically, meaning they have overwhelming desire to the point that it feels like a need to drink. Drinking too much alcohol on a regular basis can lead to a physical alcohol addiction, meaning the person has to drink alcohol for their body to function. The psychological addiction may even be gone at this point, and they not want to drink anymore, however the physical addiction is still there. Another example could be in marijuana. Marijuana can be very psychologically addictive, however it causes no physical addiction. Either way, an addiction is an addiction, be it physical, psychological, or both.
Physical dependence on a substance is a physiological rather than a psychological dependence.
