"I use marijuana for pain and want to find a strain that is good at curtailing pain but also does not induce anxiety or paranoia and does not couch lock me. Is there a strainnot cause anxiety?"
Each strain of cannabis will produce different effects based on genetics, cultivation techniques, method of ingestion as well as dose. High doses of sativas have been known to cause anxiety, while the sedative effects of indica are well known. It is generally believed that the high THC content can be responsible for the anxiety, and that by utilizing higher levels of CBD and lower levels of THC, this anxiety can be avoided. Also, the route of administration, as well as set and setting are all also of importance. Inhaling cannabis (smoking, vaping or dabbing) results in a very rapid onset of effects and this sudden change in conciousness can be startling and may cause anxiety. Therefor when smoking cannabis it is often best to take one small inhale and wait for 15 minutes before taking another. Other administraion methods such as sublingual, edible, rectal and topical can vary significantly in the onset of action and in the duration of effects. Great care should be taken to start with a small dose and increase very slowly. Set and setting refer to the individual characteristics of the user, as well the surroundings, respectively. A relaxed, comfortable and safe environment is often the best place to utilize cannabis. If excessive anxiety dose occur, focusing on slow steady breathing can provide relief, as well as focusing on an interactive task that occupies the mind. No one has ever overdosed on marijuana, and reminding yourself of that knowledge can conforting as well.
CBD strains like ACDC, Valentine X, and Charlotte's Web that have only very small amounts of THC, and varieties with 1:2 or 1:1 THC:CBD, where there is enough CBD available to mitigate the psychoactivity of THC are not likely to cause anxiety. For optimal pain relief, I would consider a 1:1 like Medihaze or Harlequin. You may feel a little buzz that quickly goes away and enjoy pain relief and muscle relaxation without mental impairment or anxiety.
