Yes
Do you mean psychologically or PHYSICALLY addictive
Yes, heroin is an opiate and is physically addictive.
Yes it is.
Both alcohol and opiates (opium, heroin, morphine, oxycodone, hydrocodone, hydromorphone, fentanyl, Suboxone, etc.) are physically addictive. As far as I know, they are the only drugs that are physically addictive. Amphetamines, methamphetamines and cocaine are extremely psychologically addictive, as well as chemically addictive, but not physically addictive. Ecstasy also has a fairly high potential for psychological and chemical addiction, but it is not as addictive as speed, meth, or coke. Hallucinogens (LSD, marijuana, salvia, peyote, mescaline) are neither chemically addictive nor physically addictive. They can be psychologically addictive, though.
Yes, marijuana can be physically addictive for some individuals, leading to withdrawal symptoms such as irritability, insomnia, and loss of appetite.
no..it isn't.
Marijuana is not addictive.
Most hallucinogens are not addictive physically, and are not very psychologically addictive. However, one of the more addictive hallucinogens is the dissociative ketamine.
No, they're not physically addictive. They may become habit forming or mentally addictive though.
It could be, depends on the person...
Ritalin is essentially speed, it's a drug. If you DON'T have ADHD you shouldn't take it. It can be addictive so you shouldn't give it to your children without consulting a doctor first.
Although cocaine is extremely psychologically addictive, as well as chemically addictive, it is not physically addictive. There are no physical withdrawal symptoms, like there are with alcohol or opiates.
