from experience yes, not only psychologically but physically too. i say this as someone who has not only sampled 133 unique psychoactives (yes i kept count) ranging from the likes of non addictive stuff like LSD to highly addictive chemicals like Oxycontin, Cocaine, Meth and a whole host of others the only ones i became long term addicted to were cannabis, nicotine and thanks to the NHS Pregabalin (which has some horrendous withdrawals)<p>youll have chills, sweats, a complete lack of appetite, be irritable and unreasonable, horrendous dreams if/when you can finally sleep. im sure its not the case for everyoe just as it isnt with alcohol for most or any other chems. addiction is in fact quite a personal thing, whether its genetic, social or psychological i cant be sure but its definitely a real thing
